I recently purchased a 99 that had rod failure on #3 resulting in a hole in both sides of the block
The car was hoared around thru several auctions by dealers before I picked it up so the past history is unknown. It has empty dual gauge A pillar mounts, a painted block, beefy clutch, receipt for crank polish and scribbles about AFR and boost in the owners manual that lead me to suspect it probably was boosted at some point. It has a header so I am wondering if it was SC <shrug>
I plopped in an 03 bottom end and a replacement 99 head and now the car will not start. There is no fuel so further inspection shows the fuel pump is not getting any power. Jumpering FP and Ground in the diag connector fires the fuel pump which we are now assuming is good.
My understanding is that the fuel pump relay is under the dash on the driver's side. Whilst standing on my head I can identify 4 relays under the dash. Two only have a couple of wires (one of which says turn signal) which leave two others that seem to have enough connections to be a contender. One of those two has a yellow connector (that I cannot get to release to save my ***). Any ideas on which one is the FP relay?
Also....if all else is well should the car run with the FP/G jumpered (the returnless fuel system is an unknown variable to me)? I am wondering if the cam position sensor, MAF, and/or crank sensor is kaput maybe? I know the NAs will not send any fuel if they do not have a CAS signal for example... Another variable is the crank sensor...the one that came with the car (in a box in the trunk...yeah...fun times) looks like this: Photo Gallery: /99miata/ready2run/mystery.JPG
and I had no luck mounting it...so I nabbed the one (which looks completely different) from the 99 engine in my 96 CSP car since I know it works
FWIW: Throwing an OBDII scanner on it shows no codes....
Thanks for any ideas
