You need fuel, spark and compression. You are missing one of those, probably fuel (bad fuel pump).
Start looking at fire and gas. Trace these two that are the main problems.
On the Vortec the computer does it all.
bad fuel injector spider
Is there a way to bypass the ECM in a 1993 chevy s10 4.3 vortec
fuel injectors could be clogged
Yes.
i belive its 160 or 180 if its a vortec
A 1996 Chevrolet S10 with a 4.3 liter vortec holds approximately 4.5 quarts of oil. The recommended oil type of 5 W 30.
No, different bolt pattern.
No. It would cause the check engine light to illuminate and fail an emissions test but it would start and run.
for this I would loosen the exhaust in front of the converter see if it will run . This was the problem with my 4 cyl s10. The convereter was clogged
click it over to the on spot but don't let it turn over (your letting the fuel pump fill that filter up) do it couple times then turn it over. and see if you set off the security light (it will flash if you did)
