Won't start in Cold weather in Warm Weather it's fine


without actually hooking up a scan tool and looking at the pid data i would say you have either a coolant temp sensor issue or intake air temp sensor issue.i have seen alot more coolant temp sensors bad than the intake air temp sensors tho.

Ihave problem with 92 gmc safari it drives sometimes during driving car buck like it.s out of gas . I'll turn igntion on and off real quick. and car drives ok. Ihave replaced fuel pump.


sounds like a bad plug wire, take a squirt bottle while the car is running then spray the wires down they should start arcing, also when you replaced the fuel pump did you replace the fuel filter

1992 gmc chevy 350 wont idle when warm


This could be a number of things but i think that your problem sounds like a vacuum leak or an EGR problem. Try listening for leaks and try un-plugging the EGR solenoid valve one time.

Truck won't start right away when its hot.


U MAY HAVE A DEFECTIVE ENGINE COOLANT TEMP (ECT) SENSOR, U NEED A SCAN TOOL TO TEST THIS PART, THIS IS NOT THE SENDER FOR THE TEMP GUAGE THIS IS THE SENSOR THAT TELLS THE FUEL INJECTION COMPUTER HOW COLD OR HOT THE ENGINE IS, IF IT READS LOW THE SYSTEM WILL GET TO MUCH FUEL AND CAUSE A HARD START, DO U NOTICE ANY BLACK SMOKE WHEN IT FINALLY STARTS?

Temp guage barely moves and runs rough just off idle


Try a full tune up.. get Bosch platnium+4 spark plugs and Acel wires, do the fuel filter and air filter(i suggest K&N) buy some fuel injector cleaner or use Marvel Mystery oil. The ECU could e gone but hard to diagnose if the car needs a tune up.

Cold start problem


I should not drop more than 5 psi overnight, if it does it lets the fuel drain back to the tank, this causes long crank times because the pump has to refill the lines and filter before injectors get fuel.

Have you replaced your O2 sensor? If not, try that.
