Engine Mechanical problem
1995 Chevy Blazer 6 cyl Four Wheel Drive Automatic 150k miles

I have replaced the egr valve, electronic ignition sensor,distributor,rotor magnetic pickup,coil, wires plugs, and this truck won't start. it won't even respond to stating fluid. there is spark from the coil, distrib, and plugs. I tried a tps,and crank sensor I even replaced the computer. it still would'nt start so I put the original cpu back on. I am at wits end. help!!! Oh I also replaced two fuel pumps,and the fuel filter.

Are you getting power to the coil?

daiwms · Posted at Mon Oct 19, 2009 9:54 am

the coil has power, as well as the distributor and spark plugs. would a defective distributor prevent fuel from reaching the plugs in a vortech engine? when I turn it over the plugs aren't wet....

No, the distributor wouldn't cause the fuel pump not to work. Have you checked fuel pump pressure? Have you checked the fuel pump relay or if the pump to see if it is getting power?

fuel pump is new, registers at least 55 psi at strader valve. there is every indication power is surging through the plugs, coil, and distributor. all the fuses work. I assume the relays are functioning because the fuel pressure reg. is allowing the fuel to reach the strader valve. What next? School me plz.

If you have spark and fuel, it should run unless there is a timing problem or compression problem. Will the engine start with starting fluid?

no it will not start w/starting fluid. however, I did use a noid light. it indicated that there ws no power to the injectors. what now?

Usually that indicates a bad PCM (computer). However, I recommend checking wiring and connections.

THe odd part about this is you have spark to the plugs and it still won't start.
