Ford 7.3L Power Stroke (1999-2003) :: Hard To Start When Cold With Leaking Injector O-Rings
Truck is a completely stock 2002. New injector o-rings, glow plugs, valve cover harness, and injector cups a year ago... all motorcraft parts. New batteries and starter in the last 6 months.
I've checked the GPR both at the relay and harness got power all the way to the valve cover harness on all 8. Injector buzz test sounds okay as well.
Had a stuck IPR issue a few moths ago that caused a CEL and died while running. Took apart and cleaned the IPR and CEL is gone truck runs great once started and has correct IPR pressures in all RPM ranges.
Truck runs great once it is started and is not sluggish until warm like when it was hard to start when cold with leaking injector o-rings.
Buick - Regal :: Rough Idle / Misfire On Cold Start - Leaking Fuel Injector(s)
1991 Buick Regal, 3800 V6
Having a rough idle on a cold start. After some research and closer inspection of the vehicle, I'm quite certain I have at least one leaking injector that is flooding a cylinder and causing the car to misfire on a cold start. I'm also not at the gas mileage I should be at.
So I'm wondering, is fuel injector replacement as straightforward of a job as it looks? Any major issues I could run into in doing a replacement?
I'm planning on replacing all six injectors (I can get them for $50 each buying online with a discount code), but given that the vehicle is so old am I better off just replacing the faulty ones? I'm assuming pulling the spark plugs and seeing which cylinder is wet will tell me which I need to replace.
And one more question: Is there a way to depressurize the fuel system when I park the car for the night, thus preventing fuel (or most of it) from leaking into the engine until I get this fixed? I've read that just unscrewing the gas cap can depressurize the system.
Escort :: 1988 EXP Rough Idle - Fuel Coming From Injector
I have an '88 EXP Escort with the non-HO 1.9L
I was noticing a rough idle (vibrating, sounded like it was bogging down)
I changed the plugs, wires, cap and rotor. Still happening.
Noticed that my o2 sensor was unplugged. Plugged it back in. Still happening.
Went to check the air filter and noticed the insane amount of fuel that was coming from my injector.
I am getting horrible gas mileage (8-12mpg)
Here is a video of what I am seeing: [URL] ....
What would be causing that much fuel to be sent out?

View 1 RepliesFord 7.3L Power Stroke (1999-2003) :: 2002 F350 - Hard / No Start At Cold - Injector Buzz
This is an issue I started chasing after having all the injectors replaced on my aunt's F-350. We had them replaced due to hard/no start on cold (dealership told her they needed to be changed). Unfortunately, I did not get the buzz test results before changing the injectors.
So far that has been replaced:
Injectors
ICP (was leaking)
IPR
both UVCH
IDM (twice)
The issue we are having right now is that only 2 injectors (#6, #7) buzz properly. Initially when we changed the injectors, it did start but didn't seem to run quite right. We did the buzz test and at that time and injectors 1,3,5,6,7 would buzz strong but the rest were weak. After some forum lurking, we suspected that the IDM was faulty. We purchased a refurbished one and after we changed it, only injectors 6,7 would buzz strong. Thinking a faulty IDM was sent it back for a replacement. While waiting, we decided to put the old one back in figuring it would go back as it was before but only 6,7 would buzz strong. We receive the second IDM and same thing, only 6,7 buzz strong. We did a continuity test from the IDM connector and they all get 2.7 ohms (it was an older multimeter so not sure if being .1 under the 2.8-3.6 range is bad).
What I did next is use the uvch external pigtail to test the injectors. I plugged the extra pig tail into the uvch and then the ends of the wires into the plug of the upper harness. Afterwards, I would swap a different injector wire (on the pigtail) to the #6 injector wire (on the upper harness). Whatever injector that would go to #6 would fire correctly. So I know that the injectors themselves are fine. I am suspecting the wiring harnesses (upper/lower) but the continuity test would say otherwise. We also do not get any fault codes except for the EBP occasionally (waiting for a new one). I am lost on what to test or look at next.
Start - Gmc - Jimmy :: 1996 - Won't Start Even Replaced Fuel Injector?
I have a 96 GMC Jimmy that will not start..... I have replaced the spider fuel injector and now I get the right fuel pressure. I have random non regular spark that is very week. I have replaced the ignition coil, spark plug wires, spark plugs, distributor cap and rotor, cam sensor, the ECM, and the ignition control module. The crank sensor checked out to be good. I do not know where else to check...

View 1 RepliesCivic - Honda :: 2000 Doesn't Start And Leak In Fuel Injector Valve
My car does not start (cranks only) after I clean the fuel injector and intake manifold.
so I check the spark with tester and it is fine.then I check the fuel pressure with tester and the pressure shoots to over 42 psi without starting (normal between 38 and 46 psi) and slowly drops to 10 psi. I install fuel injector (FI) with new o-ring and gasket and there is no leakage aroung them. the fuel pressure regulator is ok. I got one from junk yard and the test show the same.
I notice there is some gas inside TB and only way to leak the gas is the FI body valve. I took all FI out and notice #2 and #3 are wet on the FI nozzle tip and use small string to push air through and can see some fluid coming out from the nozzle tip.
I thought I clean it well and do not know if this can be fixed by more cleaning. the resistance is all the same at 12.6 ohms under room temp at night in north CA.

View 10 RepliesFord 7.3L Power Stroke (1999-2003) :: 2000 - Hard To Start On Cold - Oil Leaking?
20 degrees out this morning truck not plugged in, didn't want to start had to cycle 4-5 times, each time waiting for glow plug Light to go out.
Finally cranked didn't sound pretty but cranked. Once it started idling on its own got out and seen a puddle of oil under the front of the engine drivers side center kind of.
Got up on the truck and shined a light in the valley and seen a puddle in intake valley. Heres my question? Where did this oil come from? Once it warmed up it quit and oil kinda disappeared from valley???
I had turbo off a few months ago because I thought I had a bearing down in it, but found some bolts lose. When I put turbo back on I broke the wire plug on front of the pedestal so I just left it unplugged. Very hard to cold start now that that is unhooked.
Did leaving this unhooked create a hard cold start? Should I put another pedestal on it with the plug or install one without it? Also will it hurt to leave plugged in overnight?
Ford Fuel System :: 1971 F250 - Gas Leaking - A Lot Of Crank To Start - Rebuild?
I have a 1971 F250 automatic with original stock 360 engine (100k miles). It currently has an Autolite 2100 2bbl carb.
The Autolite is leaking gas out somewhere where I can't see the leak. It takes a lot of cranking for it to start after sitting 10 minutes and my wife won't drive it for fear of being stranded. My attempt at a rebuild must have failed... Also have issues with anti-stall dashpot spring coming off while driving. When the spring and plunger come off I have to hold the gas on a little to keep from stalling while stopped at a light. A couple other parts looked like they needed repair during the rebuilt, but the kit didn't have any replacement (vacuum diaphragm torn). Also, after replacing plugs, plug wires, replacing points with Pertronix Ignitor 2, a new rotor, and distributor cap, it still doesn't hold a steady idle. In fact it is hard to get it down to the spec idle for an automatic without fear of stalling.
To make a long story short, what is a low maintenance 2bbl (new, not rebuilt) replacement carb. The truck needs to be dependably started by my wife for garage sale runs and home depot trips. I could switch to a 4 bbl intake, but would rather wait for another 50k miles and switch the engine over to a rebuild 390 with nicer intake and carb.

I recently replaced a bad head gasket on this car. After putting the reworked head back on the engine and putting everything back together, I can't get fuel to the engine. I cheated and took the intake manifold out and bolted it to the head and then set it back in the car plugging my injectors back into the manifold once in there. I checked all my electrical connections and they are all good. I am not getting power to the fuel pump, which was replaced a year ago when I first started tinkering with fixing the car. I get power to and from the inertia/fuel cut-off switch, but it doesn't appear to get to the fuel pump. I checked all the injectors to make sure they were seated properly which they were and all the fuses both under the dash and hood that I know about and then some. When I pull the 30amp fuse under the hood, and replace it, I do hear a sound that sounds like something is pressurizing or pumping for a second or to, but the sound is from under the hood and not from the pump/gas tank area.

I have researched a little and believe i have a leak in the high pressure oil system. My 2004 Excursion 6.0 will start when it is cold but after warming up will not start it just cranks over. So here is my question; the two wires leading from the Turbo had melted and shorted and in fixing that i loosened what i believe to be an oil line feeding the Turbo. Could this be the problem? Also is there an O-Ring that seats the line into the block that may need replaced?
