Toyota MR2 Message Board - View Single Post - Fuel pump not working and alternator removal

Mister Two 2 · 10-30-2009, 12:03 PM

I have just acquired a 1986 Mk1 MR2 which has been standing unused for 4 years. I have checked it over and find the alternator is seized and the engine won't go!

I have a Haynes manual and the Toyota manual on CD, and an inspection pit in my garage.

I have read the posts on this site diligently and wonder what I've got myself into! I've got a long grounding in vehicle restoration but some of the MR2 stuff is . . well . . !! So please could you seasoned MR2ists answer a couple of questions to get me started:

1. Is the alternator removed from the top or from underneath the car?

2. I have established that there is a good spark but no fuel pressure, or any noise from the pump. I've done the various checks, bridging Fp and B+ etc, and removed the console to check for power at the fuel pump connector. (This I presume is the yellow plug with two wires: white/black and light blue/black). I have power to the light blue/black wire when the key is moved to 'start' and the engine cranks over, and none when the key is released to the 'run' position.

From this I deduce that the pump is not working - are there any other checks I should do before tackling the unenviable task of tank removal??

Is it best to remove the tank over the pit for good access, or any pitfalls (sorry!!) to that plan??

All advice gratefully received - thank you!
