[hotrod0872]

got a truck thats a little hard to start,and thought i may need to check pump timing.
if i understand right you have to have some sort of computer to adjust timing.
what do i need to get?where do i get it?
thanks for the help!!

If it is hard to start, may be you need to check other things first unless you get a code indicating that your timing is off.

Doing the Checklist will help you test some easy stuff first?

I am not trying to prevent you to do timing, you cannot even do any timing if the truck is not starting. It has to be up to temp.

If yours is OBD-II, you need a scanner software. There was a discussion about it recently on a software called CarCode, etc.

OBD-I have only one choice, a software called GMTDScantech, the paid version.

Plus some tools to move the IP.

A lot of knowledge on how to do it. Usually, it gives a code when your IP is not time correctly. For people who does not know how to do it, it usually messed it up more than fixing it. Don't mean to scare you but better make sure you know what you are doing.

The InstaHeat GP made by WAP is a suspect. If it is new, they are great but it is ranked low on reliability.

Your 96 should be OBDII which means you could use a scanner such as a Tech II, Car Code, Auto Enginuity, or a Snap On (and maybe others) to first read your current timing and TDCO and to then move the pump in one direction or the other (depending on your first reading) to correct your timing so that you can achieve a TDCO of -.5 to -1.94.
