How to test mass air flow sensor on 1992 jaguar vanden plas


If a spark has no path to discharge, it will often find a weak one or create one. If your wires or plugs are so bad that they cannot pass a spark, the coil will discharge elsewhere. It is a great coil. I have seen brand new plugs completely disable an engine. Completely. I have seen wires completely fail on their maiden voyage. The plugs were Champion BRF52 on a Ford, the wires were Belden for a V6 Mercury. I do not recommend Champion plugs, at all. I do however like Belden quality. You would not suspect them, but... Suspect them. Pull one out lay it on a steel part of the engine, and see if it sparks. If not, replace them. For wire, try to start the engine at night, watch in the dark for arcing wires. Replace them.

My 90 model m azda mx6 is idoling rough


There are MANY things that can cause an engine to idle rough. It could be faulty ignition parts like spark plugs, distributor cap, ignition rotor, ignition wires, coil, worn distributor shaft, bad ignitor, etc. It could also be something simple like a vacuum leak. It could be internal engine problems like burned valves, leaking piston rings, blown headgaskets, etc. etc....So, take your pick and start replacing a BUNCH of parts trying to figure it out, or take it to a qualified technician to get it properly diagnosed.

1993 Ford F-750. 7.0 fuel inj. PFI type. No start, has good inj. pulse,psi good etc. No spark, reman. dist.,coil and firewall ign. module has been replaced. Both modules tested ok. Wiring-Help!!! ...


Hi, I do not have wiring diagrams for the F-750, but I'm assuming the ignition systems are similar for all trhe F series trucks. Are you getting battery voltage to the coil when the key is in run and start? If not, first verify the fuse is good. If there is a noise capacitor on the positive coil wire, remove it temporarily while troubleshooting. If that cap is causing low voltage to the coil, replace it. If you still cannot get power to the coil, the problem may be the ignition switch. If you have power to the positive coil terminal, pull the coil wire out of the distributor and lay it on the engine where it has about a quarter inch gap to engine ground. Turn the key on and momentarily jump a ground wire to the negative coil terminal to see if it will release a spark. If the coil will release a spark this way, the problem is back in the distributor. Was everything in there replaced? Please let me know if you have questions.

Car has no power. showed a engine missfire code , new plugs and wires .no code and still no power to hit 20mph.


Does it have the 2.2 engine?

Replacing the plugs and wires, while a step in the right direction, does not insure there is spark. Start the engine and remove each spark plug wire, one at a time. Use something well insulated to avoid a shock. You may find a plug wire that makes no difference whether it's plugged in or not. This wire has no spark. Trace it back to the coil that it's plugged into. Replacement of this coil may fix your problem, unless there is no power getting to it which is a whole 'nother ball of wax.

1999 Mercury Cougar 2.5 V6, had a cracked head and/or blown headgasket. Had the motor replaced now it is skipping on one cylinder.


pull the leads one at a time from the coil pack. if you pull a spark plug wire and the engine rpm doesn't change and there is a weak or no spark the coil pack is likely the problem.

Not getting spark


Testing the coil packs.

1. Get an INSULATED wire and hook it to a ground on the car.
2. Get some one to help you
3. pull a spark plug wire off the coil
4. hold grounded wire close to, but not touching, the part where the spark plug wire connects
5. keep hands away from coil and have your helper turn the engine over ( start car and turn off)
6. if there was a spark between the wire and the coil pack it is good. if not, the coil pack needs replaced
7. replace the spark plug wire
8. test the rest

I think that the coil packs has installed wrong because you said that the problem started when you replaced them... so i think you should re-install.
