Check fuses for fuel pumps, and the crank angle sensor on the back of the motor. Also check fuel pressure to make sure you are getting any fuel at all.

Also check fuel pump relay (white one in back of the fuse panel behind the cig ash tray). They last abaout 10 years and then they quit.

Ignition module failer


Check fuel pressure. And check for vacuum or air leaks- vacuum hoses, intake manifold gasket, the big air boot to throttle body assembly. Any trouble codes?
How is output from HT now? Do you have a blue snapping spark at the spark plug wires now? If spark is weak, it might be a crank position sensor- it can be tested to some extent, and should have a reference voltage to it, about 5 volts.

Was there only one ignition coil to be replaced or did you replace all of them? How do you know its due to intermittent spark and not a fuel delivery issue? The ignition control module is a good next step if you have changed all of the coils and confirmed it is not a fuel issue.

95 lincoln cont. occassional crank fast ,but no start ,intermittent ,later will instantly start as should


I think what you have going on here is a failing electric fuel pump, this is what they do when they are worn out, it is a rotary pump and the rotor sticks due to worn bearings. To confirm this get a can of spray starting fluid from any auto parts store, next time it won't start spray it into the air intake hose to the engine, if it fires right up you have a bad pump. The fuel pump is located inside the fuel tank, remember to also replace the fuel filter when the pump is replaced. Also check the connector to the fuel pump cutoff safety switch for signs of melting, replace the switch and connector as needed, this is caused by a defective fuel pump drawing excessive current.

It doesn't sound like an ignition module or crankshaft sensor because normally problems with either would result in a no start condition. My first thought is a loose or dirty connection in the wiring that causes an intermittent lack of fuel or ignition.

Have you checked for spark first? Sometimes a car won't start due to no spark. This condition is usually caused by: Security system, bad ignition module, crankshaft sensor, camshaft sensor. You check it by pulling a plug wire and putting a screwdriver in the wire to see if it arcs. If it is getting fire look for the fuel pressure release valve usually located on the fuel rail, looks like a tire valve stem. If it shoots out gas, and you hear the fuel pump prime, check the fuel pressure regulator. It could also be the timing. There are four things needed for a car to start: fuel, spark, timing, compression. As for your question, as far as I know there is one fuel pump, you have to drop the tank to fix it. Hope this helps.

Car will always turn over, but will not start on certain days. At first i thought it could be due to dampness and faulty wireing. When it does start it runs smooth. The other day it started in the rain....


next ime you dont start there should be a fuel tester shrader valve just like the tire shrader valve crank it and if it doesnt start check the fuel shrader valve see how much fuel comes out and if it dribbles you need a fuel pump and filter. also the 1989 are populat for intermittent due to the ICM recieving low signals, and the theory back then was what went out first spark or fuel. ICM and cam sensor and crank sensor was just replaced, Now that was the fuel injected part, 1989 there was still carburator that was being made at that time and the popular breakdown was fuel filter getting plugged.

My Trailblazer started idling and running rough intermittently. We thought bad gas. We were on a trip and used a gas teatment to get rid of water. Did not help. Delaer thought the same but now says...


I'm guessing you have the 6 cylinder engine and not the 8? I don't buy what the dealer told you. If you're really worried about a little water in the fuel system, run a bottle of Seafoam through the brake booster/ gas tank, that will solve any water in the system. Change your fuel filter after you do this, it will be dirty now, due to the Seafoam cleaning your gas tank. Wondering what would need to be "sealed" if there were a little water in a cylinder due to bad gas??? There are 6 coils on this engine, one per cylinder. If the coil goes bad, you would get a check engine light for a cylinder misfire and it would be consistantly running rough. Since it your problem happens intermittently, I'd check the wires going to the coil for any faults. I'd also check for a possible 02 sensor starting to go bad.

1 thought, does this only happen when ever you happen to have the defroster on, or the A/C? If so, I can help you solve your problem easily.

No start


To 'No Start':

If your car is not starting, and you have checked the distributor thoroughly, and all the wires, then check under the cap to see if your module (black somewhat boomerang in shape) is working or not. I have an 85, and after agonizing over what the cause was, I learned it was the module under the cap. To replace cost about $300.00.
