Need Help!

[Mike Warner]

Have a 1981 Cj7, with 360 AMC and Howell TBI. Fuel injection is dumping fuel down the intake. Had it to 2 Shops. Neither shop could figure out the problem.
Anyone out there know a Fuel injection Specialist?

This system should not be all that difficult to diagnose... It's basically nothing more than a 1987-1991 Chevy C-10 computer calibration & throttle body, thus using GM diagnostic tools, you should be able to find the issue fairly quickly...

If you do not have the GM diagnostic tools, fear not,... If you have the MIL light hooked up & functional, you should be able to read codes out of it to aid with the diagnosis also...

Here's a link to Howell ...

And if you go to thier help section... here's a link to the installation and trouble shooting related info that should help...

Here's a quote from the above installation & troubleshooting sheets...
"We use two GM part number ECM’s (1227747 and 1228747) for most installations. These are the numbers used in most TBI engines from 1987 thru 1991. They are rugged, proven designs, the result of millions of GM dollars spent on their development. They have the ability to learn a calibration that perfectly matches your engine, and retain it in memory. They also employ back-up modes that keep you from being stranded in case of an engine sensor failure.

An added benefit of the GM ECM is its ability to alert you to potential sensor or electrical problems with a “Service Engine Soon” light, built into all of our harnesses. This light and a common paper clip also allow you to diagnose any reported problems retained in the ECM memory. Procedures for this are outlined in any GM TBI service manual, or the Howell service manual that accompanied your TBI kit."

HTH... Good Luck...;)
