I'm even more surprised than you, that'* why when I woke up this morning I couldn't wait to take for a test drive to see if it was a dream.

Hey it burns rubber again.............lol

Only thing now is it starts second try when it'* cold, but hey that'* 10 times better than before.
Thanks for helping me with suggestions theJMFC. I appreciate it.

the second starts may be due to the modulator

What modulator? I wouldn't think that the tranny modulator could affect engine starting (unless it had ruptured and was pumping ATF into the intake, but I don't think that'* the case), but I'm drawing a blank as to what other modulator you might be talking about. Did you mean to say "moisture"?

And please, call me Jon.

Nope, vacuum modulator can cause 2nd gear starts. Did on mine with the old one. And it still works, even though it leaked atf hardcore [don't ask how, i was just playing around].

I found mine to more 'shift early' than anything. Like at 15mph it would shift or something, then ever downshift unless i put the gear selector in 1st.

it can also be a number of other things too... but the modulator is first on my list. It is crucial to a proper running transmission.

Sorry guys but I'm abit lost here since the conversation seems to have changed to refer to the 2nd gear in a transmission. When I said Only thing now is it starts second try when it'* cold, but hey that'* 10 times better than before, what I was referring to is the fact that it takes the second attempt at cranking it over in order to start the engine. If I try to start it during the first crank then I have to wait approximately 7 to 9 second before it start to engage....then start.
But as I said before, I'm happy that it starts alot sooner than before.

The next fix on my list is to repair a stripped guide pin on the front caliper mounting bracket ( if that'* what it'* called) that I will attempt to repair by reeming out the housing that holds the caliper in place then installing a helicoil, since the guide pin is in good shape.

Wish me luck and thanks again guys and gals.......lol

Oh, wow this is embarrasing. I thought you meant the car started out in 2nd gear. What you can try for starting it on the first try, is turning the ignition on, leave on 5 seconds, turn off, turn on, wait 5 seconds, crank. Just a suggestion.

Ah, that clears things up.

As for the long cranking time, you still might want to try to get your hands on a fuel pressure gauge. I'm told that low fuel pressure can cause that, and since you've already recently done a tuneup on the thing, that'* where I'd look first.

I tried that and it didn't seem to help.

I guess that'* worth a try, I still need to try to get a hold of one.

Thanks again guys, I can always count on you.

Well I picked up new guide pins and helidcoil, but the helicoil ended up being the wrong size, oh well back to the autoparts store.

By the way , opensourceguy how did you make out with your tranny?

Got the right Helicoil and extractor, it came in a kit all except the drill bit which is 29/64. Fricken thing was listed at over $75.00 before taxes....had to talk em down to &50.00.
The sad part is I only needed one helicoil.........awwwwwwwwwww. oh well. It worked
