There is a fueling test in the Bentley manual. I did this when assembling my 2.0l Caddy.
It required pulling the fuel injectors and placing them in cups. I placed mine in four individual glass jars. Then I made a jumper wire which replaces the Fuel pump relay underneath the dashboard. Once I have this jumper in place, I then place the key in the ignition and turn it on. (But don't crank the motor!) Then at the Fuel distributor, I remove the boot and using a magnet, I grasp the air plate and slowly lift. This simulates airflow and the fuel distributor will begin sending fuel to the individual injectors. This test demonstrates two things. 1. That there is fuel going to the cylinders. 2. That the flow from each cylinder is equivalent in volume. It will also become obvious if an injector is dirty of clogged. -Les -----Original Message----- From: [email protected] [mailto:[email protected]]On Behalf Of Larry Velez Sent: Saturday, August 27, 2005 4:29 PM To: [email protected] Subject: RE: [a2-16v-list] Backfire then Dead Hi 16Vs, An update on my troubleshooting. To recap, the car left me on the highway and will not turn over. It will crank normally but will not start. Today I changed the cap, rotor, plugs and ignition coil. I also checked the timing belt and all the teeth look normal and it seems to be turning normally. We found no spark on the plugs which is why we decided to change the ignition coil. I think the next step is to check the distributor more closely. What are some basic tests of the distributor? Also, any chance that it is a fuel problem and not an ignition problem? Would a fuel problem prevent the car from starting at all? Any other suggestions would be appreciated. thanks, Larry 91 GTI 16V - Currently out of commission. ________________________________ From: ProFormance [mailto:[email protected]] Sent: Friday, August 05, 2005 11:58 AM To: Larry Velez Cc: [email protected] Subject: Re: [a2-16v-list] Backfire then Dead Then I'd leant towards the distributor.. Ive never seen a broken belted motor turn over at normal speed. Good luck and keep us posted. If it isn't the distributor and/or cap/rotor, then we'll go from there.. But right now, that's where I'd place my money.. _______________________________________________ a2-16v-list mailing list [email protected] http://mail.a2-16v.com/mailman/listinfo/a2-16v-list For list archives, see listinfo link above.
