Ignition not firing

Do you have fuel, is your fuel pump working. If you do not have any spark at all, have you been able to check to see if you have power to your distributor. If so and you do have some then it might be either your ignition coil, pick up coil or your ignition control module. Your pick up coil in in your distributor under the plate. The coil is on top of the distributor cap. The ignition module is right under the cap where all your distributor wires connect to. Some part houses can test your ignition module and let you know if good or bad. Good luck.

My 1992 gmc has no spark and the fuel injectors dont work. why?

Check to see if when you removed the main plug and reinstalled it none of the metal fingers were bent in the computer. It has happened in the process also add some dielectric grease to keep them from grounding out.

1992 GMC 1500 will turn over but not start. I changed heater motor and disconnected computer behind dash reconnected everything now truck won't run . why

Did you disconnect the battery before you disconnected/ reconnected the under dash computer? These devices are extremely sensitive to power surges and most are not "hot swappable" which means that they need power removed before you connect or disconnect them.

Low price oil pump 92 silverado chev 1500/350/extended cab

Don't skim on a low cost oil pump. I've seen too many failures due to trying to save a few bucks. External parts maybe but NOT INTERNALS. Pay the extra for a good oil pump. A thumbs up would be greatly appreciated if this answer is helpful to you.

Oilpressure gauge indicates low to almost no oil pressure

You may want to hook up an external oil pressure gauge
to the engine to ease your mind. This would give you a regular number of the pressure. Compare it to the factory gauge in the dash. Those in dash gauges were not all that precise. If the engine is not having bearing noise I can see nothing to worry about.

Gm obd1 codes 32 and 43

Code 32 is a problem with the EGR solenoid, and code 43 may be a problem with the knock sensor. Code 43 can set when the knock sensor is functioning correctly too. You would need to get the troubleshooting charts for the codes to determine the problems.

Running ruff and cuts off

that is called MISFIRE (im not arguing words but this word works best for diagnosis) misfires and stalls. 99% needs a tune up, ever do a tuneup this decade? the 60k mile is big time important and nobody does it and car then runs bad. the PCM EFI on car does all it can (huge efforts) to prevent all stalls. so if it does stall, it's very sick. (engine power loss, big time.....) if not, turn up related?, its over 50 causes. we do like 5 tests or more with tools (simple gauges and meters) and true cause is discovered. Do you want to guess, or test, ? do say.

How to put on oil pump on 1992 gmc truck

It's not a terribly difficult job...Oil pan and anything in the way needs to be removed. Assuming it's an 8cyl, the pump is bolted to the rear main bearing cap. You may need to lift the engine to gain sufficient clearance to get the pan down. Most failures involving the oil pump are not the pump, but low pressure caused by either an obstructed pump screen or worn engine bearings, so make sure you aren't changing the symptom instead of the cause.
