Thread: No start

  1. #1

    Default No start

    Finally trying to get the SVO running. Everything is pretty much new. I’m not getting spark when cranking. It gives me a small jolt when I stop cranking. I’ve swapped in a known good ignition switch, distributor and coil. Still no go. This is an LA3 swap. I double checked my pin swap. What does the computer need to see from which sensors. Does the computer send a signal to the pip or tfi to fire off the coil? I have 12v at the coil w the key on. I also have 2 wires at the tfi w 12v but one powers up while cranking. I also see a resistor wire on the - side of the coil. Last thing...looking at the wiring diagram it says the wiring to the distributor goes thru a breaker less ignition module...is that the same as the TFI? Because the plugs they call out on the diagram don’t look to match anything in my wiring harness.

    Yes , breakerless ignition , is the tfi.
    Have you set the distributor and rotor to tdc ? Try bumping up the advanca a bit .

    Check for the injectors firing. If the injectors don't fire, then something is messed up in either the pip or tfi. Could help pinpoint wiring issues.

    Injectors are firing. I have a wiring issue somewhere between the pip and the ecu. If I pull the spout I get full spark. So I’m willing to guess that the pip signal isn’t getting back to the computer.

    So, what codes does the computer pull up?

    If a sensor isn't working to the point the car won't start, it should probably be throwing a code.

    Went and bought a new TFI plug harness from NAPA this morning. Rewired everything up to the strut tower including all the grounds at the battery. Fired right up. [URL][https://youtu.be/ET23IobAEW8/URL]
