I had the same issue on my '86 Bronco. Change the ECM(computer) and your problem will go away.

Have u checked for vacuum leaks or poss leaking EGR valve? use carb spray around the upper intake manifold where it bolts to the lower manifold, spray vacuum lines where they are connected to the engine vacuum ports, the idle speed will change if u hit a leak, as far as the EGR valve goes see if it gets hot at idle, if it does it is leaking, if all checks ok replace the O2 sensor, but i suspect u will find a leak at the upper intake plenum.

SOURCE: 89 ford probe, 2.2 turbo, no spark.

Check out your "fuel cut-off switch" located by the windshield washer tank behind the driver's side wheel-well panel in the trunk. It's a small box with a push-button at the top. If the button is "soft" when you push it, that's probably your problem. Replace the unit by removing the washer fluid tank first. The box simply plugs in. Probably about $ 100. I replaced three in my Probe. They rot out, and the car simple dies.

SOURCE: 1984 Ford E-150 Econoline van It has no spark

check the wiring around the distributor i don't know how simular it is to a 1990 ford crown vicktoria 5.0 engine,
but on this car, there is a little two 2 prong plug beside the distributor no wires coming from the plug it's self , it plugs into the wiring harness it works like a fuse.
if you remove it or if it has melted the car WON'T START, no fire the link can be removed to keep the car from starting for testing purposes (fule pressure ect.)
when you wouldn't want the car to start

1989 ford bronco 2 ignition problems maybe


It could have a weak or failing ignition coil. The other thing I can think to look for would be an exhaust restriction.. (clogged catalytic converter)

What about the fuel filter?? was it replaced?

Replaced cps,distributer(cap,rotor,cam position sensor)checked coil good still no spark,replaced coil wire and plugs is the computer next?ignition control module is in the pcm i think


If the check engine light does NOT come on when cranking at the times when it won't start, then your ECU is in need of repair. The engine will only start after the check engine light comes on and the ecu is what controls that. It's likely going bad, causing the delayed start problem typical of early 90's jeeps. Repair or replacement services for your jeep ECU are available on ebay.

Truck wont crank. we have put new distributor cap, rotor button, coil pack, plugs, wires, and fuel pump. we also checked our firing order.


you said you repl dist cap that means you don't have a crank sensor you have electronic ing module. remove your elec ing module have it tested most auto parts stores could test your module, or check your coil at the neg terminal. should have power. if not you lost your primary volt from your batt.your secondary power is coming from your electronic ing module from the module to the pos terminal on the coil, when the eng cranks,from the coil to the dist cap , from the dist cap center to the rotor then out to the plugs,this all happen pervided the timing belt or timing chain is ok. the cumbustion chainber needs 3 things , thats fuel, air, and spark.

My truck was running good when I parked it but now it will not fire, I have replaced the cap, rotor and coil but still not spark. I have fuel at the rail and the engine cranks. What next?


Replace the ignition module,make sure the rotor button is turning,remove the cap,and turn over the engine,if the rotor button is not turning,then,the timing chain is broke.

Weak spark + 1988 ford bronco


check the voltage of the b+ terminal of the ignition coil (primary side) with a cheap multimeter while cranking. low voltage to the primary will cause low voltage on the secondary. also recheck all ground paths from the ignition module. ensure good connection from coil to module. note: new parts are not "known good parts" until it runs.--> IG.MOD.
