I have a 1986 for t bird and some times it will crank others it wont and when it wont the fuel pump dont kick on when the switch is on and also it dont get no spark but every thing else comes on and it will turn over please help me!!!!
It "won't crank?" Meaning, it won't turn over, or it won't ignite?
If it won't turn over, then it is likely the battery or starter or ignition switch.
If it does crank (turn over) but won't start, and you are specifically not getting any fuel nor spark, then it is likely the hall effect sensor (see "control module" and "pickup coil"). It is two pieces, both on the distributor. Total cost will be around $50 ~ $75 or so.
You'll have to take the distributor out to get to the device, then set timing to complete the job.

It should be either no Spark or no Fuel. Possible causes: Out of gas, no oil pressure, faulty oil pressure switch, Bad fuel-pump, fuel-pump relay, needs tune-up, defective ignition control module, wrong air/fuel ratio, defective IAC valve or EGR valve. Other causes: Wrong timing, bad compression, or clogged CAT.
I'm assuming your not getting fuel pressure. Does it crank over just fine but, acts as if it's out of fuel? Sometimes the electric fuel pump saftey switch (that's suppose to stop the flow of gasoline to the motor in the event of a roll over) can be randomly triggered in this model car. The switch is located in the cab, under the passenger side dash. Pull back the carpet under the glove box, it should be about a foot down from the top of carpet. It may be a little closer to the side kick panel. It will look like a fuse switch with two wires running to it. If I remember right one wire is red the other blue.Check if the switch popped up. Reset the switch. Remember if fuel pump has been dry for awhile it may take 30 secs or so of cracking over before the fuel pressure builds. Hope this helps. If not I'm sure I could figure it out with a little more info. I've owned 3, One 86' and two '87's. Great trucks once you figure out the little strange little quirks that Ford did with the Bronco II.
checkout the crank sensor give these websites a try www.alldatadiy.com and www.autozone.com if all fails stop by your local library and get your hands on a Haynes auto repair manual for your Van wish you the best of luck Michigan Man.
modern gas formulas break down rapidly and will clog and deteriorate most fuel system parts. drain your tank. replace fuel pump and strainer sock, fuel filter.its also a good idea to run a quality fuel conditioner for your first tank full
