Most likely it is the ignition module or the crank pickup.

Maybe a problem in the fuel pump circuit. Check fuel pressure with engine off, and key turned to on, not start. If no pressure, diagnose the pump circuit at the fuel pump relay. One terminal for the relay would be the power feed for the pump. The engine computer signals the relay on for 2 seconds with key on to prime the system, also signals during engine cranking.

Engine wont start but its in fuel system


When you turn the key to on, not start, do you hear the pump turn on for a couple of seconds to pressurize the fuel system? If you do, check fuel pressure with a gauge, should be over 50 psi if multi port injection, about 20 psi if throttle body injection. If pressure is good, you may need to check the fuel injector circuit.
If no sound from the pump, you will need a voltmeter or a test light to check the fuel pump circuit. First check the fuel pump fuse. Then check for power at the gas tank on the fuel pump wire, when the engine is being cranked over. Power should be going to the pump then. If nothing, move back to the fuel pump relay-need to check for power at the relay.

1990 s-10 4 cylinder 2.5, 5 speed, throttle body injection, 120,000 miles won't start without stating fluid. Runs fine after started, I've changed fuel pump, filter, plugs. I appreciate any help.


My first question would be is the injector spraying when you crank it ?
The way its supposed to work, the fuel line to the tank should have about 10psi of pressure before you crank the engine. When you turn the key on the pump gets power for 3 seconds to boost the pressure. The pump stops working until the engine has oil pressure which takes a few seconds.
If the base fuel pressure leaks back to the tank, or the pump relay is not powering the pump, you won't have any fuel pressure or spray until you get oil pressure.

1985 grand Marquis acts like not getting fuel to start but if I pour gas directly into throttle body starts right up and runs what could be problem


Runs on the gas you pour in, or keeps running until you turn the key off ???
If the fuel pump relay fails, you would have to crank the engine until you get oil pressure to provide power to the fuel pump.
Do the injectors spray when you are cranking it ? Have you checked fuel pressure when the key is turned to start ?

I have a 1999 dodge ram was running but stalled and wont start back has started flooding the plugs with fuel and wont start unless i take the fuel relay out


What is liter size of engine? I don't know what relay you unplugged? Your fuel pressure sounds too high? If you have fuel return line, if it gets clogged, it could cause your fuel pressure to rise.
It is your fuel injector pulse width that controls fuel, If pressure is too high, it could cause a problem. Usually voltage to fuel injector, goes hot with engine cranking. The computer controls fuel injector ground.

Will 87 s15 2.8l throttle body sorta run if fuel pump bad? changed fuel filter it was totally cloged. fuel ran out line with filter off- key on. engine will run a little. dont wanna waste time and money on...


If the punp is bad it won't run at all. Check the throttle body injectors to see if fuel is coming out of both injectors. Sounds like one of the injectors is not working. If one is not working you can check to see if it is the injector or wiring by switching injector wires and see if the problem changed from one injector to the other.

No Fuel at throttle body


Fuses first.
Then, disconnect the fuel line at the throttle body (unless there is a fuel pressure testing port) and see if there is fuel when you turn on the key.
If not, fuel pump, probably in tank. (assuming there isn't one on the side of the engine..)
If there IS fuel in the line, then the computer may not be engaging the injectors. Check for wiring issues on something that old. Maybe the main junction splice for power to the computer. (Not sure where on that one, sometimes it's in a dumb place, like near the battery and it gets corroded).
