91 hyundai excel with no spark from coil

What about the condition of the battery? Try checking for spark with a fully charged battery.

check other fuses

I've heard of an excel with problems with the signal from the computer not keeping the fuel pump on, if I recall, that was on a '91 excel. To check yours, you would need to monitor the fuel pressure with a fuel pressure gauge, when the car was running, and still hooked up when the car strops running. If the pressure drops when the car stalls, you know you have a problem in the fuel pump circuit. The owner of that '91 excel had replaced the computer once, and believed he needed another. Don't know if this is your problem, but a good place to start is with the fuel pressure test, especially right after the car stalls. If it turns out not to be fuel related, then probably something in your ignition.

One reason your 91 Toyota pickup 3.0 v6 has no spark is because you battery could be dead.---------------------------------------------------------------------------------

It is usually in the fuse panel under the hood. It's easier to disconnect both battery cables and hold them together for a few seconds. Reconnect the battery cables and the ecu will be cleared

You describe an issue which should be diagnosed by an authorized and certified Hyundai Technician. Here's what happens when a coil fails: Overload of the drivers in the in the PCM (Powertrain Control Module) as well as the IFS (Ignition Failure Sensor). Did you happen to have a "Check Engine Light" and did you retrieve the DTC's (Diagnostic Trouble Codes) from the PCM (ECU (Powertrain Control Module/Engine Control Unit)? I'm going to assume you had a coil failure.... occurances like this also damage the IFS.. when that happens, usually, it also damages the coil drivers in the computer (ECU/PCM)... this is why I recommend you have it diagnosed by a qualified Hyundai Tech.

check ignition coil current supply and or distributor contact point or condenser/ ur cars current supply fluctuate when engine is hot....

hi there, is it carby or fuel injected?

CARBY - fuel pump, dies when warms up (most likely if you still have spark)-to test for spark remove a lead and stick a small screwdriver in and sit a few mm from an earth point(dont touch the metal part of the screwdriver) turn the car over you should see spark.
- needle and seat
- fuel filter (not likely)
- coil (if no spark when test)


FUEL INJECTION - i would go straight to the ecu, the 1990 is renound for having a **** ecu, they blow capacitors real easy and carry on in wierd and wonderfull ways. hope i helped.

Sorry to tell you this if you dont already know its the ecu, take it out take off the cover and youll see the main capacitor in the center (its a black capacitor with grey markings, there are a couple of others similar located around the board but this one pretty much in the center) of the board has black suit around it and on the board, if your carefull a $3 capacitor (your local **** smith electronics will have one) and solder it in making sure you get the polarities right. unfortunately with these model cars it is a major problem, but if you are not confident with the work email me at matmenzies.adam.com.au and i can referr you to an ecu recon joint for around 85 they will fix your ecu, NOW the problem, there will be a reason why the ecu blew, it will be simple like cracked lead or wire earthing somewhere on chasis, you see the smallest earth spike, even from say turning the car over too much will blow that capacitor. sorry for the bad news and i hope i have been of some assistance.

it coul be the ignition module in the distributor or depending on the model it could be the transistor unit
