Mk2 golf track car - Getting the old girl back on track......

I had a bit of time this morning to play with the car.
I get a reading of around 200 rpm when cranking, I've got a spark but no fuel from the injectors. They are getting 12v but don't squirt any fuel. (Removed from the car & in a tub to check). There is definitely fuel getting to the fuel rail but no further.
The coolant & air temp sensors work and show believable values on the screen.
Any ideas where to go now? Possible the injectors are blocked & need cleaning after years of sitting idle?

Thanks

 

200 rpm. Good! Crank sensor is working - Next.

Sparks good - Next

Injectors are getting 12v supply so good, your electrics are as you left them. - Next

No injection? What is the pulsewidth on cranking? Is the TPS in the position for "Flood clear" ?

Look at the TPS in live settings and see if it is reading WOT/or 100%. This can happen and you would never start it.

 

I had this once, turned out to be the settings for cold start were a mile out.

Then another time the TPS died.

I think the pulse width might have said 6 when cranking but will check. (Should have videoed it ????).

I think the flood clear was set to 178 and the same window had cranking that said 300, which I also tried at 200.

What's good settings for cold start?

Not sure why it thinks my car is 350cid 8cyc?
Changed but not 100% on the injector size...

 

Software suggests the injectors should open.

Do you see them work on the Stim?

 

No RPM or pulse width on the stim.

 

Might have a dodgy pot on the stim, it doesn't feel great & if I wiggle it I can get the gauges to briefly indicate something.



Soldering iron required to swap it with a known good one.

 

Swapped over and still not working ??

 

With the injectors removed, when you turn the ignition on do you get the Fire Priming Pulse ? That should give a short spray from all the injectors.

That`s just turning the ignition to II not trying to start it.

 

No, I'm getting nothing at all from the injectors.

 

Just over a year later & after some Megasquirt faultfinding by Toyotec she runs :-)

 

Jeez, didn't know it takes him that long to fix a Megasquirt problem.

 

you probaby won't see this, but worth seeing if you kept the car and did more?

 

I'm also interested in hearing about it. I run a Rally car in the States with very similar specs and love it.
