Hi there:
You will have to prove out the wiring to make sure there are no shorts, opens, or poor connections. If there are no wiring problems, then the EEC may be at fault. The crank sensor produces an AC voltage signal that may be getting corrupted by the time it reaches the ignition module, due to bad wiring. Make sure to verify whether the ignition module is receiving a clean strong signal by using an oscilloscope or at least measure the signal with an AC voltmeter at the ICM connector while cranking the engine. The voltage will vary with speed, you are looking for a steady signal that doesn't drop out or become erratic. You can run new wires, and make sure they are not connected to possibly shorted sections of the old wiring, by cutting the old wires off at the connectors and connecting new wires to the cut ends. Or replace the connectors and wiring if you suspect that the connections are bad. Inspect carefully for damaged terminals that won't make a good tight connection with their mating pins when connected.

Here is a basic diagram of the entire system, it is common to all the distributorless units even though this one shows a 6-pack coil.

First I sugest to check to see if the check engine light comes on key on engine off. Chekc the EEC Power relay in the fuse box switch with another relay (underhood fuse box, called PCM power relay). Check ground connectiosn.

Bmw troubleshoot


Hi, You need to check for fuel and spark. Spray starting fluid into the air filter then try to start it. If the car trys to start then you have a fuel delivery problem, could be fuel pump or filter maybe even wiring for the fuel pump like the relay. If after spraying starter fulid it won't start then you need to check for spark, pull a spark plug wire and place a spark plug in it, ground the side of the spark plug to the metal part of the engine, have someone help, try to start the motor and look for spark at the end of the spark plug, if no spark then you need to check the electrical system and the timing belt. log into the local libary web site and find the auto reference guides for you r car that may help also, Good luck.

Have a 2003 Mazda Tribute having intermittent starting problems. It will turn over but not start. Also it will die while driving every now and then. Have replaced IAC, fuel filter, and fuel pump works...


You need to determine what you are losing when the car won't start - either spark, or fuel.
Check for spark with a spark tester at one of the spark plugs. If no spark when attempting to start, you have an ignition system problem. If you have spark, but the car still won't start, you have a fuel delivery problem.

1990 Cadillac Seville won't start. Is it the electronic control module?


Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.


To confirm the problem, the basic troubleshooting is required.

Car will not start, engine turn fast enough to start. swapped relays still would not start. 2003 madza tribute.


Check if you have a spark by pulling the spark plugs and crank the car while the spark plug is on the ignition coil/spark plug wire and ground the threaded part of the spark plug and ask someone to start the car and look for a spark is a spark is present then ignition is fine. If spark plugs are wet and smell like fuel there is problem in the ignition system.
