My 89 car stalled multiple times on highway 5 on the drive to Disneyland 2 weeks ago. The car would intermittently loose power then just shut off on the freeway, like a bad Mass Air Flow sensor problem or bad fuel pump. But then when I coasted off the freeway at the exit, the car started up again after checking wires and re-seating plugs on the MAF. So after the 3rd stall and lot of huge trucks driving by, I just called a tow and got the car over to 928 International late that Sunday night.

Monday morning Dec 30th, Mark at 928 intl let me try a new MAF but the car was running fine anyway. Strange. One interesting comment was that the 89 car will run with no MAF connected. That is not what we discovered. The car stalled immediately when we disconnected the MAF. Both of them (A spare one from Mark's shop) My 85 and 87 cars also both stall immediately when I would pull the MAF connector off. So that theory seems to be incorrect.

So in the 928 intl parking lot, after tinkering around with wire harnesses and checking the fuel line wires, fuses and relays, I could NOT get the car to stall again as it did 3 times on highway 5. So off to Precision, Greg Brown's shop to check things out. Thanks Mark for the referral.

We found the crank sensor was kind of beat up and the connector was totally fractured. But the car still ran fine. So Greg pulled the fuel line under the car, dumped the fuel and primary in-tank pump out to discover very constricted flow at the in-tank pump, which by the way had stopped working.

So after a few hours, a new crank sensor, a new "S" fuel loop under the air cleaner area and a new in-tank pump cost me a few hundred for parts and $197 labor. What a very reasonable deal and fast super hero work on the part of Greg and his team. The 25 year old "S" shaped fuel loop was pretty high risk and cracking, so that was just a precaution. The in-tank pump seemed to be the primary problem if not both that and the crank sensor together. So hopefully my secondary overheating fuel pump is not permanently damaged from the clogged up and failed in-tank pump. So far, no problems after a couple weeks.

I'm wondering if the fuel injector cleaner I used a month back was part of the problem. (getting the car smogged prompted the injector cleaner) I think that stuff is not so good for fuel pumps because my 85 car also had a failed fuel pump just months after fuel injector cleaner was added. So... not going to do that again!

Anyway, the trip to LA worked out. Off the Disneyland the next day with the wife and the car runs like a dream all the way back to the Bay Area. Thanks for the help Mark at 928 international and Greg at Precision!

you couldnt pick a better team, glad your back up and running.

I've never heard of a car leaving Greg's shop with a problem unless it was the owners choice not to fix it. Cars come in for this or that, and the owner will say oh and it does X but "nobody" has been able to fix that, and you can see something light up inside Greg, problem nobody else could fix, goodie goodie (ok maybe no goodie goodie, but it gets fixed).

Superhero's wear spandex, where are the photos?

While it's a little more comfortable to have a snooze in the passenger compartment there is a certain "feeling" you get from napping in the engine bay...

Note he doesn't have some super special way of approaching the problem. He just gets in there and does it. That's key people, that's key.

Good not to show his face. Superheros always hide their true identity.

Over here at this time of the year shorts is not suitable to wear when the cars have spike tires.

That was a visual I did not need.....



Plus Rob is that what they call "twerking" ????

I think the kids call it 'dry sumping'.

You and Greg in spandex wearing capes.........

This could go somewhere with your Hollywood connections....

That is so begging for a Graham photoshop. Thinking early batman/robin outfits.

To the untrained eye it looks like somebody laying on a 928 engine and working on it. But actually it is a super hero levitating above the 928 engine and working on it.

Anyone have some good shots of Greg and Jim we can submit to Graham?
