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 |

Quote"Will probably need to pull the injectors and crank to see if they are in fact pulsing fuel. It puzzles me that I do not hear the enrichment injector pulses when I open the throttle, especially when everything else is checking out on the wiring."unQuote
You can put then in jars to see how much as well, and remember spark plus open fuel = danger.. be cautious; And for me I never hear the injectors unless someone else turns the key while I have my head in the engine with not ta lot of ambient noise.. Quote"When you re-installed the motor, did you connect the fuel lines correctly? (inlet hose-outlet hose)... Nice to know another VA 914..."unQuote Excellent point!!, I hate to admit it but that one got me!! I tried everything else first only to find that I had un-crossed the fuel lines (where the factory fuel pump location was) when I re-installed my engine thus cause the fuel to run wrong way in the engine compartment, no start.. doof!! Check your routing.. This pic is for the 2.0 but you should get the idea... ![]() |
