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 |

Bryan, I unclog mine on the bench with a 3.0 volt battery ,some parts wash and compressed air. Just fill up the injector with the cleaner, use the battery to open the injector, and then shoot the air through it. Do that about 1/2 dozen times. Should clean them out.

A few years ago when I tore into the car, this did not work so I sent them in to Mr. Injector. It was quick and cheap. All four came back spot on for flow rate. He included new screens, pintel covers, painted them, new upper and lower seals, and threw some Jolly Rancher candy in the box (not sure about that though). It was good to see numbers on the flow report. If you do it yourself you don't know for sure how balanced they are after many years of use. Brian BTW....I loved driving a 914 for the first time ever. It was worth the wait. Glad I put the time into the car. |
