3SGE Poor Idle and Engine Dies @ 2500rpm

[Roundy]

Hi All,

Just gone through a week of doing work on my 92 3S-GE MR2, doing a whole lot of maintenance to fix oil leaks, replace timing belt and clutch. But throughout trying to resolve an issue where it is hard to start, won't idle, and dies/stalls at 2500rpm and won't recover.

Working through it, the dizzy cap and rotor had a lot of pitting, so I thought I'd found my problem, but once all back together it is still there.

What I've done is:
New timing belt
New clutch
New crank seals and oil pump seal
Injectors cleaned and tested
New dizzy cap and rotor
New leads
New plugs
Tried another TPS

I'm totally stumped as to what the problem might be. Anyone got any suggestions?

Kind Regards
Nathan

Sounds like a fuel supply/pressure problem. You need to check the fuel pressure in the rail and then check the flow OUT of the FPR (return to tank side) by using a spare bit of hose and running the fuel into a clear glass bottle. Get someone to crank the engine briefly (or just turn the ignition ON if the pump primes) and make sure there is a strong jet of fuel into the bottle. Keep a fire extinguisher handy
