Hi guys I own this soarer and one day I went to start it and it will fire but then shortly after firing and running a little rough she stalls (about 5 seconds) ive pulled all the air intake off and rocker covers and replaced all seals and gaskets and run the fuel pump control module bypass through the diagnostics plug but still nothing ive just replaced the fpcm and dash panel today and just waiting for the battery to charge to see what happens but thought you may have some other thoughts on whats going on

The first thing to check is to take a reading on the fuel pressure using an accurate gauge.
Also scan the computer and post any stored code numbers here.

Thanx for the reply mate the code im getting is engine electrical system so I looked around on the web and found a site called all my crazy lexus issues solved as toyota made a replica lexus soarer as u would know and found that a common problem resulting in most issues with them is leaking capacitors in the engine ecu so I pulled mine apart and sure enough 3 or 4 of the 10 have leaked and one has blown a diode also I think so ive ordered the new caps and im going to get a qualified solderer to put them in and see what happens ill keep u posted on how she goes thanx again
