The Cursed T4

Thanks Jimmy. Yeah it was DOA.
I agreed to look at it cos it is the guy who collects my scrap cars van and as it was only a 2L, I thoughtit would be easy! Always the way huh.

Sometimes the crank pulley for the timing belt wears the the cast in key,so the cam and ignition timing go out far enough to prevent running. Pull the covers off and check and see if the timing marks line up.

Peter very good point mate , seen that one with a TDI Audi 80. We set up the valve and pump timing then ran it, it would run ok then turn to crap. All the timing out again. Thats what it was a stripped keyway.
When you check all the timing does it need adjustment or is it bang on????? Sounds like the timing is out a mile, as in 180 degress of ign timing.
I know what it feels like to start throwing stuff on to diagnose. Might pay to start from the absolute basics again. Fuel , Air and spark at the right time and it should go ( but i dont need to tell you that, just talking out loud) So Diz cap off and set up number 1. Valve timing at number 1 ( incase you are 360 degrees out) and check the rotor arm is pointing to number one on the dizzy. (hasnt stripped belt teeth and belt still intact at the same time?????????) Wish i was there to help ya. Being DOA did it just die or progressively choke????

Have you checked the knock sensor (s)?

I've seen enough dead knock sensors and they don't seem to make any difference to normal running and starting except under heavy load and the pinging doesn't stop

I like this one, happened to me with my G60 Passat. Plenty of spark, lots of fuel, no running.

Check the timing marks.

Can't be the oil pressure cos Matt wouldn't get any compression readings.

The bottom pulley does not have marks on, so we made our own by pulling no 1 plug out and feeling with a screwdriver. The Cam pulley has the mark directly upwards which lines up with the mark on the cover.
Then setting up the dissy and should start.

I guess the top could be 180 out, it has apparently been somewhere else for a clutch and to be made to start I hate taking on secondhand problems.

Maybe I`ll try turning the top 180 tomorrow.

I have rebuilt the starter from three dead ones, so hopefullw will be able to start the biach.

I`ll keep you posted.

Mate in doing so take the cam cover off and check the lobes are pointing up, incase you are full revolution out. Take the bung out the gearbox bellhousing and line up TDC there, the diamond cut out or O/T lines up with the pointer.
Good luck man

Maybe so. However, If I purposely disconnect the knock sensor plugs on my Caravelle, it will not start.

Anyway that it for my suggestions.

Ok, so today I removed the fuel rail as the motor still sounds real fuelly.
Took it apart to change the injectors.

The only replacements I could find have a different colour on the top. From a Golf 3 2L. How different could it be? Whacked em in and no.1 was pouring with fuel, took it all back out again and changed the split o ring. all together and it nearly starts.

Nearly, but not nearly enough. Am wondering if it is the wrong size injectors. I reckon it should start and run rubbish at least. Have all the batterys on charge and am gonna get some aeostart tomorrow and try again.

Anyone have any input?
