When my son turns the car (87 turbo)over there is a good spark every 3 or 4 seconds not what I would expect(I only know convental motors) . Would this be an ignitor problem? When I see a spark it is decent.

 

What exactly is the issue?... Is the car not starting?

What other syptoms are you experiencing?

 

Car will not start. When checking spark there seems to be one (spark)every 2 or 3 revolutions. Wonder if trying to start it with a low battery hurt something?

 

^ It won't hurt, and it definitely will not help.


Nothing has recently been changed on the car? (Crank Angle Sensor hasn't been moved or messed with?...) It has just started doing this??

It's possible that the car is flooded and/or the spark plugs may be fouled. (Probably from cranking it so many times to start it.) - Try removing the spark plugs (inspect them and clean them thoroughly. Set them aside... Do not reinstall them yet.), remove the 40A "EGI INJ." and 30A "EGI COMP." fuses in the engine bay fuse box, turn the car over (four times, ten or so seconds a piece) so that it can spew that unburnt fuel out from the spark plug holes, now install both fuses and *clean* spark plugs. Attach spark plug wires, and perhaps use a battery charger with a "Start assist" function. Now, try starting the car.

 

Have you looked at your grounds and plug wires? I had some strange ignition issues years ago. Some of the grounds had abit of corrosion .. I cleaned the posts and replaced plus ran a couple extra grounds and it cleared up. A resistance check with a dmm can quickly eliminate them as the culprit.

 

Are you getting fuel?

 

Are you getting fuel? If its just turning and not catching at all I would suspect fuel . I would listen for the pump to kick on for a second when you first turn the key on. If you don't hear it I would listen for the fuel pump relay to click when you first hit the key . It's in the drivers side rear corner of the engine bay , between the master cyl and fender.if it clicks then check for voltage at the fuel pump . If it doesn't click then it's probably the relay . Pull the oval connector with 2 wires off and check for 12 volts at one of the pins. If it has voltage but doesn't click it's probably shot. If there's no voltage , then there is a 15 amp fuse in the fusebox by the drivers foot . I think it's labeled "engine" . That controls power to the relay. Twice I've had it go on seperate cars.

 

Car is getting fuel. I don't understand the spark (usually spark then no more for 3 or 4 turns then I see another one.s as soon as the car starts to turn over)

 

Is this occuring on both coils? The coils need to firmly bolted to the fender to be grounded properly. Have you cleaned the connection to the CAS? Is the battery properly charged?

 

Or even the ecu not grounded properly... From my experience coils usually start to breakdown When they warm up.. Thats just my experience tho . If its not fuel I'd start checking all your grounds and go over all the connections with contact cleaner

 

Changed the crank sensor and the care fired right up. Thx
