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.

SOURCE: bmw 1988 325is engine stops running sometimes -

The number one problem with these cars is with clogged fuel filters. They must be changed regularly. When you say it won't start, do you mean it cranks but won't fire? That could be a fuel pressure problem due to a clogged filter.

SOURCE: engine wont start no spark......ignition control

I had a car a couple of years back do this to me, it was the crankshaft sensor. It will not fire at all if it is bad. Luckily the part is really cheap.

From your description it sounds as if you have insufficient current to support the electronics and lights . Check the condition and of the alternator drive belt. Have the alternator output checked . If you have continual jump starts then unless it is done correctly there is a chance that the ECM is damaged . But everything points to a low out put from the alternator

I syphoned gas from my car and now it wont start


1st thing ,make sure you haven't taken out too much gas out. ck.fuel filter. loosen fuel line up on carb. or fuel injection ,whichever it has. If able to get to turn over see if fuel getting to engine. If not,fuel pump bad or fuel filter plugged. If able to get car started, disconnect batt. If it dies, alt.probably bad

Car wont start


I can only say that for the old cars even sitting for a year is not healthy, because most parts of engine, starting system, charging system will get corroded/deposited. Most probably you will need to change battery, motor oil, fuel, spark plugs, check the starter and alternator. Also check the fuel pump, fuel filter. First shot would be battery, fuel, spark plugs and starter.
Good Luck

1989 ford f350 diesel wont start


If the truck has good batteries and cranks well.--- There is a schrader valve on top of the fuel filter housing, (it looks like a tire stem valve) depress this valve while someone cranks the engine until you have fuel flowing out of this air bleeder valve. From that point, crank until it starts. Do not crank more than 30 Seconds, then let the starter motor rest. After you have this air out it usually startes in one or two tries.

When was the fuel filter last replaced? What precedded this no start condition? Was it running fine?

Agin, this truck must crank quickly in order to start

good luck
