Help! Misfiring

[kelsres]

My 4 runner is misfiring and won't tick over.
It's a 1992 V6 VZN Automatic with EFI.
I've had the AA look at it and discovered that its only running on the 3 righthand cylinders. Compression is ok and the plugs and leads on all 6 cylinders are firing so it looks as though it might be a fuel problem.
Is there anything that I can check for myself ?

Sounds similar to a problem I had on my 4Runner turned out to be ignition leads not knowing any better paid £100 for a new set from my local main stealers. Fixed the problem though, wish I'd known about Milners then. By the way mine seemed to be firing on all cylinders however it seems that it wasn't on every revolution. Worth doing could save you a lot of time.
