This is my barn car that has been sitting for 30 years. It is a 1970 1.7L stock D-jet FI. I pulled the engine and also the FI wiring harness to freshen up some sheathing and a few terminals. Here's the list of FI and ignition repairs/replacements done. Engine back in last month and still sorting a few things out...
The engine did run (rather poorly though) before all of the following. -New plugs, wires, points, condenser, rotor and cap. -New blue coil -New fuel pump and hoses -Added fuel pressure gauge in line. -Fuel pressure at 30psi - jumpered fuel pump at relay to set -New vacuum hoses -Verified all ECU connections using Bowlsby's checklist on his site (although had no help to verify both trigger points operation while cranking - not cranking, had one side open and one side closed) -Fuel injectors were sent out about a year ago for cleaning - were put back in and run but have been sitting since then (possibly clogged??) -New vacuum advance/retard canister -Static timing done and points gap set for initial start up. The engine will turn over easily by the starter and will run for a short burst on starting fluid. I do not hear the "brrrrrrr" or "clicks" of the FI's clicking as the throttle is opened (i did verify that the TPS is connected and working while going over Bowlsby's checklist). Are my FI's stuck or clogged, ECU dead, what else?? (IMG:style_emoticons/default/headbang.gif) Where next? I am so close to getting this thing on the road after about 2 years of sorting things out. I would greatly appreciate any direction. Thanks guys! Brian |

I'll throw in the good old "timing is off". Had similar issues when getting mine fired up for the first time after going from carb back to FI (even had the "it started with starter fluid" symptom). Everything tested out fine - just had to keep playing with the distributor until it fired right up. Kinda hard for one person to do (end up flooding the engine) - very easy to check with two people (one turns the key, the other turns the distributor until it starts).

Mine started fine until the cold weather set in. Had to turn the distributor until I found the right spot to catch. Thought it was my plugs but I see yours are new. And probably a good idea to look at the trigger points and make sure the contacts are clean. Still working out my own problems but it's worth a try. |
