    I was at Checkers today and they have a scan tool for $150, your choice of GM, Ford, or Chrysler OBD1. I think they are made by ProScan, or something like that, will call and check. I was wondering if anyone has any experience with this or other budget scan tools. Thinking about going in on one with a couple buddies.

    Thanks,

    Pete

    Pete, I've got the Auto X-ray scanner from <A target="_blank" HREF=http://www.autoxray.com/scanners.htm>http://www.autoxray.com/scanners.htm</A>. Picked it up at Checkers for $150. It works sweet! Just make sure you get the latest model, as pictured on the web site. One Checker I went to still had the old version on their shelf. [​IMG] You can tell the difference by the keypad. The layout of the older model looks totally different.

    Mike, these things actually allow you to look at the data from the computer in real time. Way more info than just a flashing light in the dash. It's an awesome troubleshooting tool! You can see exactly what's going on. Many times the "error codes" are nothing more than a symptom of the real, underlying problem. With one of these tools you can get the actual readings from the sensors to see what's really going on under the hood.

    Thanks. I'm trying to get my brother's TPI GTA to run worth a crap, but would like to have one for the Blazer too. Pep Boys says they have one for $100, will probably go check out both after work tommorrow. Harry, it there a picture of the keypad one yours somewhere (so I can tell which one they have)? What's the difference between the two?

    I can't find a decent picutre on their web site any more [​IMG]. But what you don't want is the XP240. The new model is called an EZ-Link. Checker uses the same part number for both of them. :-(

    I'v got a auto X ray scanner too. It works great. Its worth every dollar it cost. Used it the other day on a buddys truck. He had taken it to a shop they charged him $300. And they still didn't fix the problem. Plugged in the scannner.No trouble codes showed. But the Operating data readings wer'nt right through the o2 sensor. Replaced the sensor and fixed the problem.
    Then we went to the shop raised H### and questioned the competence of their mechanics in front of their customers and got his money back.

    Whatever you look at, it appears from what I have seen and heard of scanners, you want one that will give you "real time" data. I looked at one on closeout at a local chain, and it did not give real time data. Check online for comparisons/reviews before buying.

    The Auto Xray EZ-Link does do real-time data and also has a data capture mode for intermittent problems. I'm most impressed with mine. [​IMG]

    This runs on a laptop and interfaces with every GM OBD I (up to 1992) computer...it's really neat and only costs $149. Lifetime support and upgradesi ncluded...can do logging, etc.

    I have it and am very satisifed with it.

    Bought the Auto Xray EZ-Link yesterday, forgot to get batteries. Came across the fuel pressure gauge in the garage yesterday, decided to give it a whirl. Bingo, fuel pressure is 24 psi, spec is 40-47. Was too dark to find the cause, suspect the regulator but should find out for sure tonight.

    Pete, be sure to disconnect the vacuum line to the regulator before testing the fuel pressure. The vacuum line causes the pressure to drop at idle, but 24 PSI sounds too low, even at idle. [​IMG] I think that when stock, my TPI ran around 35 psi at idle and 42 psi disconnected.

    Was following the procedure outlined in the HELM manual. Didn't mention disconnecting the vac. line, it should develop and hold 40.5-47psi when not running. I tried cycling the pump a few times as well, it builds and holds 24 psi.
