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 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.

No spark at plugs

Do you mean you get spark from coil high tension wire to dizzy cap? If so, the only thing left is the cap and rotor and wires and the engine must have a good ground.

Suzuki wagon r+gl check engine light keeps flashing and wont start after battery change

the engine (there are more than one engine)
has a distributor.
"have spark at coil down to dizzy but no spark at plugs"
this can mean only 2 things.
1: spark wires are dead. all 4, kinda hard to believe huh?
2: the dizzy is way off time. so time the dizzy and now spark
lands on each wire term.
if not a dizzy engine, post exact version of engine and country.

I have a 1990 Nissan pintara 2.4liter I can start it then stop straight away I've replaced coil dizzie cap and leads do u think it could be fuel pump or dizzie any help would help thanks francis

The place to start with this problem would be to scan your onboard engine computer for fault codes. If there are no fault codes present, then see if it will stay running if the throttle is opened slightly. If it does, then the problem is most likely caused by a bad Idle Speed Control (ISC). These fail sometimes without setting any codes.

My hyundai excel wont start unless i pour water on top of engine (black plastic doodah). how or what do i replace? thanks paul

Hi Paul

I'm very surprised pouring water onto the engine makes it start, if anything you are pouring water into the sensors, electrical wiring and surrounding the spark plugs. Water and electricity shouldn't mix, ever.

Check the distributor cap for any cracks - replace if there is.

Check a spark is getting to the spark plugs by holding an HT lead (one by one) to the engine block, crank the starter and if you see a spark that lead is OK, repeat for the other leads. If there is no spark, change the coil or coil pack.

Once you have established a spark then it could be fuel related. Check the injectors are wet after you have pumped the gas pedal. Hold the throttle wide open and try and start the car, if it starts then you timing could be out.

Adjust the timing with a timing gun.

I hope this helkps you and please vote for me and please don't pour any more water on your engine :)

96 model hyundai excel stalls while driving my 97 hyundai is stalling after driving for 10 min ive changed the coil spark plug leads and plugs the fuel pump still work ive pulled it out and tested it...

we had a hyundai once, that stopped and started for no apparent reason , after much looking at and mechanics it turned out to be some butterfly or non return valves leading from the fuel pump to the engine. they were closing up and stopping fuel from passing through , might be the same kind of thing . hope this helps
