Question about 1991 Mercury Capri

1 Answer

I am not getting any spark in my ignition system from a 1991 capri xr2. I have changed the coil, rebuilt the distributor, changed the cap and rotor button, and changed the spark plugs and wiring. It ran shortly at low idle and then quit, i can not get it to fire again.

Why my 94 Astro van will not fire


this generation of gm vehicles is easy to troubleshoot. the engine needs 3 things to run: compression, fuel, and spark. since you mention fire, i assume you have no spark.

disconnect any random spark plug wire and connect the end to a hei spark tester. crank engine and observe for spark. if you have no spark, disconnect the center terminal of the distributor cap and use the hei tester in the same manner. spark means cap and rotor bad or bad plug wireset. no spark means make more checks.

check for battery voltage and good ground on distributor. check for open or shorted ignition module or ignition coil windings. if power and ground is present and ignition coil tests ok, check for ignition pulses at coil primary. if you have no ignition pulses feeding the coil, change the distributor.

with that generation of vehicle, the ignition system will operate without help from the computer. don't even troubleshoot the guts of the distributor, if you change the cap, rotor, and anything else, it will be the same price as a remanufactured distributor, and might not fix the problem. if you troubleshoot a low volrage related issue (no pulses, shorted or open circuit, unstable timing, etc), change the whole thing.

I have 1991 mpv v6 3.0 engine. It will not start. I changed the ignition coil and the igniter coil. what else could cause no spark?


Several things, actually. There could be no battery power at the distributor due to a blown fuse or a bad main relay. You could have a bad distributor cap, bad rotor, bad ignition cable between the coil and the distributor cap, a bad Engine Control Unit, a bad distributor pick-up coil, or any of the wiring in-between. (see schematic)

My car has no spark it has a new crank senor i tested the ecm it passed so what could it be


it is mounted on the side of the ignition distributor body, here is a picture, u should also change the Stator inside the distributor, this requires you remove the distributor from the engine and then drive out the roll pin that holds the drive gear on, this is not for the do it yourself-er

My car isn't firing. I changed my ignition coil, but distributor still isn't getting any spark(new wires,dis. cap,ign coil)


Without looking at the diagram on our model Is suspect the pickup in the distributor has gone bad. In the early type distributors the pickups are prone to go bad but ground the wire from the coil to the cap and remove the cap, have a friend turn the engine over with the starter for a few seconds, check that the rotor button is turning !

1991 F150 quit running


You need a new distributor. You've replaced everything else. A distributor will get up and running again.
