914 won’t start looking for mechanic

[Coolaired4evr]

Hello guys . If any of you know someone in the Houston area with air cooled fuel injection experience that would like to help me fix my 914 no start issue pls let me know. I am willing to pay labor and transport fees . I have a shop so tools and such aren’t a problem . I just don’t have enough experience and time on these to repair. Let me know . Thanks for reading

Its getting hard to get the old FI parts. Have you checked the fuel pump output. It is high pressure (35psi) so could easily be the issue. Also try www.914World.com

Many just give up and convert to dual carbs. Dells and Webers are still available.

If I still lived in Dallas...I would come down and fix it for you. At one time I ended up with a factory cert in D, K and L injection.

It will be far easier to fix it yourself. Tell us what you have, what you have checked and what its doing.

We can help you fix it here most likely.

There are only 23 wires, five sensors and a few other main components that do not fall into the sensor category...fuel pump, trigger points, injectors etc.

Yes..fuel pressure...and fuel pressure stability...are critical....but its also a 100% resistance based system....and vacuum is the main load sensing device. Your vacum systems must be PERFECT.

You guys are awesome for offering to help !! Thank you so much . If I can start by picking your brain. Ok so I think I’m having an injector issue . I do know i have a 1/2 inch vacuum line that broke but I plugged it at both ends . The injectors don’t seem like they are getting pulse. Vehicle runs with me injecting gas in intake via spray so that tells me I have spark. The pump triggers on when I open flap of air flow meter . I have swapped computers , relays , checked connection to relay board. When the vehicle sits for a day it will start up but quickly die out. Can you tell me what I should be checking or if I forgot something? Thanks again guys .

If the pump works when cranking (meaning that the power does not leave in the crank position (that would be a broken ignition switch) and you have a spark, and you verified that the resistor block on the bottom of the battery stand is plugged in, then as one is cranking move the air flow meter flap further than it is moving on its own and see if the car starts. OFTEN there is a vacuum problem and the flap is not pulled far enough to induce enough injection to start. The cold start valve works at 60 degrees and colder triggered by the yellow wire connected to the right rear spade of the four terminal connection on the rear of the relay board

Thanks for all the views and help guys, I figured it out ! She starts up on a dime now! Relay wrong placement and computer I bought on eBay was wrong one.
