1987 350 motor troubles
i have a 1987 chevy suburban, i just recently started having problems. the motor at first when i hit 40 mph or so it started to bog down, now i start it and it dies after a few seconds, starts strong but just dies, now do you think this is a fuel issue? like a regulater problem, cause its getting fuel i can see it when i take the air cleaner off, but it just dies. any ideas on what it could be?1987 Chevy Suburban 4x4 - Lifes a garden, dig it, gotta keep on keepin on!

I would start with the simple stuff, like fuel filter, etc. check the fuel pressure,then move to the regulator, Just because you see fuel, does not mean it is getting enough.Dana South Carolina

I agree, always replace your fuel filter every year. You may have water blocking the fuel lines too. Usually the fuel filter gets blocked with water. Next would be the fuel regulator. Then comes the injector nozzles. Injector nozzles can also be clogged. You should have a nice spray cone and not a straight streem of fuel comming out. After replacing the fuel filter add a additive to dry out the remainder fuel in your tank. ( DRY GAS ). Old fuel tanks also have lots of sediments on the bottom and can cause blockages.

Sounds like your fuel pump is getting weak. May or may not be partially caused by the fuel filter. Either way, the filter is a quick & cheap job and should be done anyhow.
Do you have a fuel pressure tester?When you hear hoofbeats, look for horses not zebras.

Based on what you told us it does sound like a fuel delivery prob. How is the oil pressure? voltage might be a problem, without more info all we can do is guess.

the oil gauge is broken, it is getting spark, heres what happend ill give yall what i know, it drove decent on monday, then it didnt want to pass 40 mph, then tue i started it and it died after about 10 seconds, i give it a lil gas and it revs then quickly bogs. now i start it and about 5 seconds later with no throttle it dies. i take off teh air cleaner and i see 2 small streams of fuel. and it dies anyway, though im pretty sure its fuel issue.

If you are seeing streams of fuel from the TBI injectors, and not a cone shape, then your injectors are either no good, or not enough fuel.

ok that makes sense, and this is why i hate tbi and efi. i love my carburetors. but ok i will check the simple thigns first, ill replace the filter and see whats next, i idnt know it was supposed to spray in a cone shape. so thats probably a pressure problem huh? maybe the regulator?
