1994 Chrysler LHS Starting Problems

My 1994 Chrysler lhs, will start and run for apx 5 seconds then shut off.. I replaced the fuel pump, the ecm, the plugs, plug wires, coil pack, cam and crank sensor and still it will start, run for 5 secs then die, over and over for apx 20 times... then it will NOT start until the next morning... I am curious, does the BCM (Body Control Module) have to be programed to the ECM (Engine Computer Module) (Brain) so all functions such as the anti theft will work in harmony? Or does anyone have a clue of what is going on with my LHS?
Thanks

It's either a spark or fuel fault , if there is spark after it shuts down it is a fuel fault. connect a pressure gauge in the fuel line, start the engine , note fuel pressure around 35 psi , stop engine , pressure should drop a little then hold, if not check pump return valve and pressure regulator , check fuel flow , if low replace fuel filter,

SOURCE: 2001 sebring will turn over but will not start

Most Chrysler cars do have an anti-theft system that can cut out the engine.

I would call the service department, with your VIN handy, and see if yours was equipped with one, and what you need to reset it.

If that isn't the problem, your EGR valve might be bad, or the sensor for it. I've seen a lot of cars where if either the valve itself, or the sensor are malfunctioning, the car won't run properly.

I would also check your MAF and IAC, as those can cause the car to not run.

If you can, get an OBDII code scanner, and pull the codes from your car, they might give you a more specific place to look. (Most parts stores will let you take one home, you put a deposit down, and get it back when you bringthe scanner back to them)

Start up and die


If it will eventually start and run, I would check the fuel pressure at startup. The fuel pump relay provides power to the pump for 3 or 4 seconds and if the computer does not "see" oil pressure it will not continue to power the pump. That is to prevent a fire in a wreck.

I have a 95 LHS engine turns over and tries to start but wont start


The first thing is to check it for spark and fuel, try spraying starting fluid spray into the throtlebody and see if it runs for a few seconds, if it does then we know its getting spark and not fuel, this may be caused by a bad fuel pump, another trick is to have someone try to start it while you beat on the bottom of the gas tank with a rubber hammer , this will shake the pump and sometimes make a connection to start, if this works then pump is bad replace it, good luck, hope this is helpful.

My LHS wont start... if I ran out of gas-- did I mess up the fuel injection? I cant get it to start...


Turn on the key and listen for the pump to run for 5 seconds. If it does, repeat this process about 5 times.
spray starting fluid in air intake too.

1994 CHRYSLER LHS. CHANGED PLUGS, CHANGED WIRES,


Try removing air inlet hose at throttle body,and open plate up by turning throttle linkage slightly (engine off) and spray a shot ( second or 2 ) of WD-40 into throttle body, then try to start and see if it try's to start, or starts for a second then dies. If it does, you got a fuel delivery problem. Can you hear fuel pump hum at all in rerar of car when you turn key just to on position? (not start)
