SOURCE: Excessive black exhaust on 2003 GMC Sierra Duramax Diesel.

This is what i would try (cheapest first) redexe/wyyns
injector cleaner,double dose,then i have put 1gal gas in 10gal diesel to increase burn temp (you may encounter a hot start problem temporarilly)then if still smoking, get a compresion check on the engine(this will tell you volumes)
by the way the NATO tanks put in 1/3 gas in diesel to stop it freezing in arctic conditions.any more than 1/3 can result in problems.

SOURCE: 1989 gmc sierra 6.2 liter diesel hard start when hot

hi, i have seen this problem ten years ago twice, but i was dumbfounded by the answer. all details aside, I replaced the ecm, and never had the problem again with both of them. this repair was a recommended repair by the local truck depot in my town, they stated the ecm got hot along with the truck and it lost the injector sensor signal. now, don't take this solution and run with it, i haven't repaired a 6.2 diesel in ten years and i maybe off track completely. but at least maybe you could ask around your town or maybe a large truck facility about this. of course, you should take to a shop to have diagnosed. hope i could help.

95 gmc sierra won't hold steady rpm


Sounds like wiring problems with the engine harness.
The oil pressure not working could cause the hard starting problem.
The idle problem could be a faulty idle air control valve or a vac leak.
I would start with the check engine light and find out what the codes are.

1991 4.3 GMC SIERRA SLX 1500 engine starts but as soon as you go to turn the steering wheel or turn the a/c on the engine dies,have any idea ? ihave changed multiple sensors.


I would check the idle air control valve and the throttle body.
The valve could be faulty or the throttle body could have dirt blocking the air passage.
If you keep the RPM above idle speed does it still stall ?

94 gmc sierra 4.3 v6 manual, won't turn over, can hear fuel pump start when accessories turned on..won't fire, girl who needs help


The first thing I would check is fuel pressure. This type of fuel injection requires a minimum fuel pressure in order to operate. If fuel pressure is as little as one psi below minimum the vehicle will not start. You can try squirting a couple of shots of carb spray into the air snorkel while somebody cranks the engine over. If the engine starts and then dies you now you fpdeffinetely have a fuel issue. If the engine still won't start check for spark. Let me know what you find. Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!

A bad ignition module can give you fits!!!! Replace it even if it doesnt fix it! You will be glad you did! Most likely that is the problem ,however!

does the starter make a "clicking noise" when it wont turn over? check your battery cables at the battery and at the starter solenoid....if it not a connection , then it sounds like a bad starter relay/solenoid
