zzdhalla Anyone got a good EFI checklist for troubleshooting a 164 injection. I remember one from another site but lost it in the eons of time. Sparks are all fine as it timing. Runs fine on ether go juice. Splutters and Coffs but wont run normally by its self. Pump powers up and pumps well. I was going to give it a new filter and fresh fuel as this stuff is .. ugh.

volvodriverman I remember the map sensors failing regularly & those damn triggering points in the bottom of the distributor were never right in my old bus.

Angus242164 Not 164 specific, but if you've got spark, and fuel pressure at the rail, then the next thing to check for is injector pulse at the injector plugs when cranking. You can use a noid light, or an LED test light. Don't use a bulb type test light, the current draw of the bulb could blow the injector driver transistors inside the ECU.

zzdhalla Thanks Working on it this weekend will update as soon as I find something updatable.! bgpzfm142;46310 wroteThis is a copy of Volvo's original D-Jet troubleshooter. volvowiringdiagrams.com/volvo/Vintage Info/Volvo 142 144 145 164e 1800e Fuel Injection Fault Tracing.pdf Just for the record, volvowiringdiagrams.com/ has many useful files on it.
stufale Check the spark plugs - if cylinders 1 & 2 are both "sooty", consider swapping / overhauling the MAP sensor. Typical symptoms ruff - rolling engine with black exhaust smoke. If there is a difference between the color / "sootiness" of spark plugs 1 & 2 check the breaker contacts at the base of the distributor. A second way to check this is to use a digital voltmeter across the fuel injectors [1 & 2] and note any difference typically one will be of the order twice that of the other.
