QuestionI have a 1994 Galant LS Automatic single overhead cam 2.4 I just swapped out a 2.4 with a wrecking yard 2.4 motor. I can't get this sucker to start up.The car had been siiting for a year before i did the swap.i put in New plugs...wires...cap..rotor..fuel filter..pvc..oil and battery.
How much fuel should be coming out of the fuel line that comes off the fuel filter and into the fuel rail when the key is on ? should it be like a hard spray or more of a weak hose. I'm not finding the right place for my timing marks...the timing cover and the H-balancer line up and the rotor facing # 1 but it still will not even pop or snarle.I checked compression they range from 128 to 153. I put the old fule rail and injectors off the old motor soo i know they are ok. fuel pump might be weak...how do i know? fuel regulator..HOw do i test that? timing might be off how can i tell if # one is TDC without using the marks on the timing cover. I do have spark in all 4 pluggs. Could.... not having a plug ...on the transmission plugged in right or not having enough fluids stop the car from starting? neutral safty switch?
The car does turn over and acts like it want to start but it does not sputter or backfire it just turns over and over.
any suggestions?
thanks
AnswerJndfarm,
This definitely sounds like fuel is not getting to your engine. You can test to see if your fuel pump is working pretty easily by hooking a 12V source directly to the pump. I believe your Galant even has a fuel pump check connection. You'll want a service manual to show you exactly where that is.
There's a good chance your engine is not receiving fuel because your car's computer is telling it not to send fuel because of a timing issue. When your #1 cylinder is at TDC, all your valves should be closed (or all near being closed). Then, your #1 cylinder should be at it's highest point. You can test this by getting a long screw driver, and putting it in your #1 spark plug hole. Rotate the crankshaft manually, and watch when that screwdriver gets to it's highest point. With the valves closed and the the #1 piston at TDC (highest point), you should be able to set your timing to that and have enough tolerance to have your engine start; assuming your problem is a timing issue.
I'm not sure of the tolerances for fuel pressure on your particular car. But most service manuals should have that informations. You should be able to use a vacuum guage or possibly a compression gauge to get that reading.
I doubt a lack of fluid would prevent your car from starting, there's not any sensors I can think of that measure the transmission fluid level. But it's always a good idea to have adequate fluid. It will want to flow even when the car is not in motion. Not having the car in neutral or Park will also prevent the engine from starting (though if that was the case, you probably wouldn't even be able to get the engine to turn over).
So my best guess would be that your timing is off, or you're simply not getting enough fuel. Focus on those areas and see if can pin point the problem.
Good luck!
