    1993 Fleetwood will not start

    I was out driving my 1993 fleetwood brougham 5.7, I was at a stop light and my car turned off and wouldn't start back up. I had to get it towed. When I got a chance to look under the hood it sound like it wasn't getting gas so I took the air filter off to look at the injectors to see if they where spraying gas while I had someone trying to crank it no gas sprayed out the injectors, I checked the fuel pump it came on,checked the fuel and injectors fuses and relays they where good so I change the fuel pump and still no gas coming out the fuel injectors when I try to start it. What could cause both injectors not to spray?

    Could be a VATS problem, is the "Security System" light on the dash flashing when trying to start the car? Also did you confirm if there's fuel pressure in the line? I know you said your not seeing flo out of the injectors but you still need to check if there's pressure in the line.

    Thanks for replying, the security light doesn't flash. I will check the fuel pressure.

    If it was Passkey it won't crank. If it has fuel pressure a bad HEI module will make the injectors not work.

    Your computer gives the pulse to open the injector . So why is it not giving the pulse? It don't have a crank sensor so it must get its pulse from the distributor pick-up.. If the distributor pick-up is not working you will have no spark when cranking...If you have spark I would start looking at the computer...

    Yes, the sender set up is the same. What Sting is talking about is on top of the gas tank, where the metal lines of the sender connect to the hoses. Sometimes that hose can split, causing air to get in. However, the OP changed the fuel pump, so you would think he would have noticed this issue.

    Re: 1993 Fleetwood will not start

    Still haven't checked the fuel pressure, I'm going to pick a pressure test kit from auto zone in Monday morning, as far as the fuel lines splitting the look okay, thanks for replying

    ----------

    Is a HEI Module and Ignition control module the same thing ? If so I replaced the icm after getting it checked by oreilys they said it was bad.

    Re: 1993 Fleetwood will not start

    It was ignition control module that I had already replaced. After checking every thing else spark plugs and wires, fuel pressure and filter and pump. I went and took the module back off took it back to part store they said it was bad , so I had them check the new they gave me for replacement it was bad also, after the 5 part we finally found one lol. I installed in my car she started right up. That's my followup I thank everyone for taking to tome to reply have a nice day
