Question about 1990 Volkswagen Cabriolet

Open Question

1990 VW Cabriolet won't start

I have checked for spark and fuel, have both. It will fire on ether. It seems that the injectors are not firing, I am thinking possibly ECM? Don't want to spend the $300 if that's not it. Thanks in advance...

do you have compression on every cylinder? that may be your problem, that's the suggestion i'll make. pull each spark plug one at a time and do a compression check to make sure you have compression. if you don't have the tool, they are not that expensive to purchase. hope this helps you out!! although, if you do this test and it's good compression, i would lean more towards it could be out of time. meaning it could possibly have jumped time but you said the belt was good, it could have jumped a tooth or two which would mean a no start also.

I changed the fuel pump but the van still won't

And you know the fuel filter is good? Could be injector problem: just as a check, spray some starting fluid into the intake and see if engine runs a few seconds. If it does, it is a fuel problem. Check injector fuse, as a start. Check fuel pressure. Check injector circuit. If engine won't start with starting fluid, check if you are getting spark. Problem may be in the ignition system.

I have an 03 vw beetle diesel turns over strong but won't start. Tried shooting it with ether. Still won't fire. Every thing else working fine please help me to know where to start

bleed any air from the fuel system from the filter to the pump . If you have pipes to the injectors loosen off the pipe nut at each injector and crank until drops of fuel appear at each nut. If there is air in these lines you will not get enough pressure for the injector to work but as soon as you get drops of fuel re-tension the nuts If you have an electric solenoid shut down (stop) make sure there is power at the unit to activate it as it will be in the stop position until it gets power from the ignition circuit.. Do not use ether as this is a good way of blowing the head off the motor or causing serious internal damage.

Won't start 1990 jeep cherokee laredo

Technically if the engine has compression, is getting spark at the right time and fuel, it should start.
Have you checked the spark plugs to see if they are fuel or oil fouled ?
Are you getting spark at the plugs or at the coil ?
Have you tried using carb cleaner or starting fluid in the throttle body ??
Have you checked fuel pressure to see if you are getting enough fuel to the injectors ?

check whether your vehicle is equipped with any immobilizer -anti theft system- as these systems are the one which could cause these unexpected situations.

The dash gauges all work , fuel pumps are both good , the fuel pumps wont come on and the truck trys to fire when i turn the ignition on but wont , could this be a fuel regulator

did you check the fuel pressure pump on the frame rail for power and ground? have you verified no ignition spark to the spark plugs? have you checked for fire from the coil to the distributor cap? does the check engine light come on when you turn the key on? have you check for injector pulse and power at the fuel injectors? if the fuel pump won't come on and you have no ignition fire and no injector pulse, all of these systems are triggered by the ECM.

1985 VW Cabriolet. It turns over enthusiastically, but won't fire. I've traced current to distributor from coil, but no spark at the plugs. I've replaced the ICM card, given it a new...

So you have no spark from the coil or you have spark from the coil but not at the plugs. You said it turns over really fast? Have you checked the timing belt?

No power to fuel pump, relay is good, engine cranks over but won't start.

You need to follow a detailed troubleshooting procedure in a repair manual.
Check for spark plug fire during cranking after it dies.
No spark = ignition problem= computer will not fire injectors, and possibly cut out pump also.
Good spark = pump wonky, or power to pump system.
Also, other quick tests... when the thing dies, and then you crank,
1) Thump the fuel pump in the tank, if you can. A bad fuel pump might start up again.
2) Shoot some ether carb cleaner in the TB. If it only fires off the ether, the ignition system is no longer suspect.
