Check the injector relay and the injector fuse if they are good you might want to make sure the computer was programed right. and check to see if the injectors are getting a signal from the ecu

Why wont the fuel go to the carburetor on 1989 chevy 350 cdi. It has new injectors, fuel pump, and fuel filter.


The injectors are mounted in a throttle body.
If you have normal fuel pressure at the injectors, they may not be getting power and ground from the engine computer.

My car won't start I have changed the coil fuel pump fuel pump relay and the Mfi relay I now think its the crank shaft relay but I do not know help me !


Sounds like maybe the main computer is bad. When you cranked the engine there is not any indication that it is firing. If you have changed the fuel pump and coil and it still wont even fire, the computer is most likely the cause. Even if the timming was off you would still get some indication that it was trying to start although it probably would not if the timming was off, but the fact it's not even trying to fire yeah that's my take.

My chevy C3500 4x2 diesel crew cab is turning over but wont start i checked all the fuses do u think it may be at fuel pump r a line stopped up or a senser


You need air, fuel, and spark to start your vehicle. It may be the fuel pump, filter, fuel pump fuse/relay. You should be able to hear the fuel pump kick on when you first turn your key. Fuel goes to the pump, filter, lines, and engine. If it is getting gas, you need to check for spark. Spark plugs/coil wires, distributor, dist.cap, cam sensor, ect. It can be anyone of them. Check for gas and spark.
