My coil is not fireing i fix the fule pump but not getting no spark from the coil to start the engine

The coil, injectors, and fuel pump get power from the ASD relay. If you have power to the coil but no spark from the coil, have you checked the pickup in the distributor ?
The pickup sends a signal to the engine computer and the computer fires the coil.

Here's a quote from amy Chilton's manual for 1980-1987.

"Several types of fuel filters are used. One is located in the fuel tank of all the vehicles and is part of the fuel guage assembly. Second is a sealed paper element, in-line unit; mechanical system- located on the engine (above the fuel pump) or electrical system- located in front of the fuel tank. Third is a paper element, in-line fuel filter/vapor separator, housed in a fuel resevoir. Normally, the in-tank filter does not require changing. If it does, the fuel tank must be removed. "
This thing you describe sounds like the typical Chrysler in-line filter of its day. It is nothing more than the same generic in-line plastic see-thru filter you buy for your lawn mower except in the 70's and 80's it was covered in metal and had a Chrysler part number. A lot of guys added an extra filter in those days, it wasn't the best system. I would remove the outlet line and turn the fuel pump on, see if you get fuel. Replace if needed.

If the injectors do not fire, fuel in the rail does not matter since it's not getting gas into the engine. Look to see if your check engine light comes on, when you turn on the ignition. If it does not, then your ecu computer is in need of repair since it's not sending either a spark or fuel injector signal to fire up your jeep.

Think the oil pressure switch keeps the fuel pump running once started. Suggest replacing Oil pressure switch. And no it won't effect oil pressure reading when it goes bad. The switch is a safety device. When you roll it over and the oil pressure drops the switch cuts off the fuel pump. Neat huh? Need some good feedback Thanks!

You need fuel, air, and fire to start the car. Make sure you check the fuel components. Make sure they work. Fuel pump, filter, lines, injectors, pump fuse/relay. Fuel goes from the pump to the filter, from the filter through the gas lines and then to the engine. Make sure gas is getting through. If the gas checks out, make sure you are getting spark. It could be spark plugs/coils, wires, coil pack, distributor, dist.cap, rotor, cam sensor, crank sensor, ecm. You need to do a spark test. Check your timing belt/chain. Anyone of these can cause your car not to start. I know it is a lot. That is why it is important to check for gas and spark. Make sure you check all your wires, connections, and hoses. Make sure there is no intake leaks. If you have any questions, please let me know.

Good battery, good starter. Leaves spark and fuel.
1. Remove 1 spark plug wire from a plug. Hold near engine block while someone "cranks" the engine.
- Spark (yes/no)
If yes, issue is fuel. If no, remove distributor cap and check for cracks. Also clean inside to remove rust and dirt. Besure that inside of distributor cap is reasonably clean and rust free. After that, reinstall cap.
Try to start engine. IF it is exactly same symptom.....
Check input voltage to coil (high voltage source for distributor). Is 12volts present? If not, troubleshoot wiring between battery source and coil. Be sure to include the fuse for "ignition" in fuse box.
If yes.....Confirm high voltage is present at center (input) wire to distributor (CAUTION:- 30,000 volts could be present... do NOT touch bare wire.) Use insulated plyers or similar to place this center wire near engine block to check for spark. Note that this voltage source is powered on as soon as the ignition key is in the "run" position.

Replace coil if no high voltage is coming out. Replace distributor cap and rotor if high voltage is coming in to it, but not leaving and getting to spark plugs.

-------------
Confirm fuel is getting to intake.
I spray starting fluid into intake while cranking engine. It will "fire" if all else is good.
If it "pops" or fires, then you have a fuel feed problem... between tank and intake manifold, shoot fuel filter, fuel pump and otherwise confirm that gas is moving to intake from gas tank.

Good luck.

This may be a result of no fuel or no spark. To test, remove a spark plug after turning the engine over for a few turns and smell it. If it smells like gas, it's a spark problem, if not you should check your fuel lines for leaks or your fuel pump. A quick way to test the fuel pump is to put the key in the ignition, turn it to "on" but don't try to start the car and listen for the pump to "prime" the system. It will sound like a low humm.

To check for spark, remove a plug and hold it against the engine block while someone tries to start the car (only turn the engine over once or twice while doing this!). If you are getting spark, you should see it. If you aren't, check the firing order, the distributor cap/coil packs, wires, and the plugs themselves.

I hope that helps and good luck!

check and make sure you have plenty of fuel in the tank. gas light should not be on as long you have plenty of fuel in the tank unless you have faulty fuel level sensor. check if you getting sparks and fuel, pull wire and one plug out, ground it to the vech have a friend turn over the engine and see if you getting strong sparks. no sparks check coil having 12V, good coil, cam sensor faulty. check if you getting fuel, pulling hose from the fuel filter line, point it down ward wrapping the end with clothes covering the hose and turn the engine over, see if you getting proper fuel and good pressure coming out of the line using your thumb slightly cover the fuel line. no pressure or fuel, check the fuel pump, good pump, faulty crank sensor. both crank and cam sensor work the same way, one telling computer to send sparks to the plugs and other turn on the fuel pump.

these were hard to fix when they were new in 1990, question:::: does it run and rev-up hi normally in neutral/park??? with a timing light does the distributor show full advance???you claim "CUTS-OUT", like back-firing ??you may need to test the COIL, TPS (throttle position sensor) and LOOM to isolate the cause,.. try those and let me know the outcome....GL

Check your fuse and the fuel pump relay.
