VR6 WARM START ISSUE CUTS OUT

[todd]

Will more than likely be a crank sensor

Got the sensor off tody waiting for new one will update next week when new one on....

How many times have you cranked it over? It could be possible that youve knackered your ECU.

All I can say is quite a lot, I got the sensor and got some injectors so going to replace them this weekend,lets see what happens.

My one thought though is if VAGCOM can't find the ecu could be that.

What makes this harder is that this was a 16v to VR6  conversion so many moons ago and not sure if the guy rigged up the diagnostics ?

Ok got injectors and cam sensor....I hope it one of the two......
If injectors/sensor seem ok then last check is fuel pressure
If fuel pressure ok then has to be ecu related/immob related.....
If Fuel pressure is fine out comes Mr ECU and get it tested.
Anyone know any ecu specialist that can test for me ?


Cheers

Ok, done the following today I hope this helps someone one day...I'm going nuts

1) Changed cam sensor and can't tell if worked or not as car will not start at all now.
2)Pulled out injectors to see if were leaking I used 6 Evian bottles they were the perfect fit for the injectors, turned on ignition, and now have established that the fuel pump is not pumping any fuel into the rail or injector's at all now, before you could feel the fuel in the lines and now nothing so could be my issue.
3) Have taken injectors off with rail and for sanity sake will get them tested.
4) Taken ecu out and will get tested again for sanity.
5) I will post a picture when I can figure out how to do on here.

Update: ECU gone to ecutesting.com, lets see if they can pull any codes from it.....

ECU fine just got back.
New Fuel pump purchased.....

[francoisd2446]

New fuel pump fitted and the following:

1) No fuel was coming through at all which was odd as it's a new fuel pump
2)Tested connection pins using multimeter and continuity test was failing on one pin.
3) Checked,rechecked fuses and then all of a sudden a little spark on the fuse and board and fuel pump started, which leads me to believe it's the fuse board has got corroded where it has been sitting for more than 5 years.....
4) So now we got fuel again, I still hear the hissing noise coming from injectors, so got a 3rd spare regulator now to test as well as testing the injector for leaks......

For F sake you better start now b.t.c.h....
