Well, I unplugged the TPS and drove it around. Still idles on one rotor and is VERY VERY hard to start. But, it ran to redline without a problem so the TPS was too far from spec for sure.

I tried to do a compression test but the digitial tester fails. My guess is because the starter isn't turning the motor over at the proper speed, sounds like the battery is just dying.

I was going to move on to the fuel issues this weekend.......

... but after parking it for a bit and attempting the compression test we noticed a large puddle of coolant on the ground. bah. leaking from the radiator.

So tonight was an expensive night.
1 fluidyne radiator
1 walbro pump
1 haltech e6k
a bunch of fluids...

:o that 3k is departing quick. bah.

going to send the injectors out to get cleaned.. I wish I could just upgrade to 1600cc injectors now but even with the haltech I can't see those working with the otherwise pretty much stock motor :P (could be wrong though :shrug: )

oh yeah, if anyone knows why the car is so hard to start.. any opinions are welcome :P

So are you sure the rear rotor has compression? If not, time for some new apex seals.

timing is set up? I had to use ATF a few times. Also, try new plugs. I tried for 3 days to get mine to start; changed the oil and plugs, put some ATF in, and when it started, got it to 2K and held it around there until it could idle at 1500.

I don't see why you'd have major problems going with the 1600's now. If anything popped up, there are more than a few things you can do to get your fuel requirements up there where you'd need to work them more.

GOOD compression diagnosis, first. Ran to redline without a problem, as in full power/both rotors going but not at idle?

When I checked it a few months ago, it had 8.2kg/cm2 compression across the rear rotor. Since we got it back from the guy who rewired the car it's been hard to start. Going to check over his work this weekend and check starter leads.

Since I last checked the compression it has been driven.. hmm.. 10 miles probably.

Timing needs to be corrected I think. Plugs are 10-15 miles old but getting replaced anyways. Need to change the oil (planned for this weekend), and some other stuff. will try the ATF trick :thumbup:

I figured the haltech could modify the pulsewidth enough but figured I'd ask before dumping the $$ into 1600s. I guess 1600s and fuel rail will be ordered and just get 2 of the 550s we have cleaned/etc for the primaries.

Ran to redline on both rotors, softly (no boost) and full throttle (6-7psi). It is running a little lean I think so the problem may be the primary injector on the rear rotor.

any vacuum leaks will make it hard to start.
