Need some help.......engine won't start.

[Ron V]

Hi Guys,

Last time I ran the car (about 3 weeks ago) it was running perfectly. Friday night I went to start it for a warmup and checkover before heading out for the races this weekend.

The car won't start. It will kick over but will not fire up and run. I have checked the plugs and they are all getting spark. 1 and 4 look dry and 2 and 3 look wet. I swapped the wet plugs with the dry plugs and tried it again. Same result.

Swapped the Coil, wires, TPS, ECU, pulled the stator cover and everything looks fine inside.

I feel like it is firing on 2 cylinders being 1 and 4 or 2 and 3. Since the plugs on 2 and 3 are wet I think these are the problem cylinders. I can confirm that all the cylinders are getting spark. Although 2 and 3 seem weak.

I did a test on the Crank position sensor (although I am not sure I did it properly) and according to the internet it is fine also.

I'm lost. and pissed I missed the weekend.

Any help would be greatly appreciated.

I checked the spark with the plug out and holding it to a ground point. There was definitely spark on all the cylinders albeit 2 and 3 seemed weaker than 4 and 1. I did know about the wasted spark system.

Simon, I am going to try that today.

If that fails then I will do a compression test.

Thanks Guys.

I tried a completely different coil. Exact same result.

and the battery never drops below 11V while cranking. It is a Varley.

I didn't feel like seeing the car today. I went to Mosport to watch the NARRA race I wanted to run in. Spectating Sucks.

The SR8's were fun to watch. I have never seen one run before.

Back on the car when the work week relents......

I'll let you guys know when I figure it out.

Good insight Rick, mine is an 06 and every different component I tried yielded the same result.

I will get the Volt meter out when I am back at the shop.

Thanks again guys.

So to conclude............the car is running.

I tried a new set of plugs with the same result. Kicks over but wont fire up.

I pulled the fuel rail and set it all up to fire into jars so I physically see the injectors firing. Everything looked good so I put it all back together. I then tried to fire it again and it started!!!....... rough at first but then with a little gas applied it cleaned up and ran as normal. Sounds good too!

UNREAL! I have no idea why it wouldn't start. Is it possible to have an air lock in the fuel system??

Then it makes sense. I drained the fuel from the tank completely when it wouldn't start thinking it was a fuel problem.

at least it is running. I tried it again today and it fired right up.

Thanks for all the help guys.
