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've been reading this with great interest as i have a similar problem with my '71 1.7. i have fuel pressure but, nothing's triggering the injectors to spurt. i took the dist. out and spun by hand, the trigger points do signal. should i see some current at the injectors while cranking the engine (must look pretty silly, i can twist the key with my foot while holding a test light to the injector wires - gotta love that removable roof...)?
i am planning to get under the car to check the ground strap. the car quit on me while getting some junk food a mile or two from the house. had a friend tow me home. if the ground strap appears ok, should i just clean up it's contact points or is a replacement in order? semi related - my fuel pressure's low (was running fine that way), even though i have the regulator maxed and i see some bubbles in the clear fuel lines. time for a new pump? thanks to all who share their knowledge on this forum. wonder how the hell we all managed / fed our addiction / affliction before the internet?! if any fellow member needs a favor in san jose, i'm so there! paul |
