Please help me troubleshoot wht my FD won't start.
First of all, thanks in advance.
This past Sunday, after going for a drive, I changed out my dead battery for a new, healthy battery. My car was already warmed up, so I wasn't concerned with flooding the car, but afterwards, the car started up, stuttered a bit, then shut down. I figured I just didn't hold they key down log enough, but it just wouldn't start up again after that.
I thought I flooded the engine, so I did all the necessary steps to un-flood it. I even figured it was a good time to put in fresh spark plugs (all four).
Nope. Nothin'
When I turn the key, it just makes that starting sound, but it just doesn't turn over!
I thought maybe I blew the EGI fuse or the fuel pump fuse, but they're both fine. Coul I have killed my fuel pump somehow without blowing the fuse? The pump is only a year old rx7.com upgraded pump.
I don't know what else to check. how can I check if there is fuel pressure? Any other tips of what to look for?
Thanks again,
Ian

in the diagnostic box under the hood, jumper the F/P and GND terminals with the key in the ON position and the engine off. that's your fuel pump diagnostic which will turn on the pump and pressurize the system if the pump in fact works.
Remove one of the plugs and check for signs of flooding

Yes, i second that. A lot more accurate and a smarter way to check.
Possibly the engine is seriously flooded with a mix of low compression. Push start or ATF/Seafoam in the chambers is worth a try.
A flooded engine usually fouls out spark plugs.check for spark with a good ground/check if you have the right plugs and condition of the plugs.

It looks like my fuel pump is not turning on. I checked the fuse in the driver's side kick panel, and it's fine. what else can I do to check why the pump's not getting power? I can't imagine the pump has gone bad, as it's less than 1 year old and was working perfectly prior to me changing out my battery.
Any ideas are much appreciated!
Anyone have a wiring diagram?
Thanks,
Ian

will i have spark at wire, f/p primes, did nt have tools to check fuel at lines, exhaust smell like fuel-not strong but there,
you can here the motor turn and kind of a pup pup sound in exhaust from it moving but nothing acutally tries to start
did not have tool for compression testing either
bought new plugs and will hopefully be able to test some more and do plugs tomorrow...
thanks for advice
