Mr Polson 10,214 Posted August 29, 2018 Carb or injected?I'd check cap, rotor, leads and plugs firstSent from my Pixel using Tapatalk Share this post Link to post Share on other sites

Jkmacxf 24 Posted August 29, 2018 Vacuum leak. or, plug leads, cracked cap, shit fuel, incorrect timing, fouled plug, blocked air cleaner, clogged fuel filter, ignition module, coil, Thanks bear351c. Is there a vacuum advance on the injected or is it controlled through the ecu. Air filter clean , new fuel filter and a tank full of 98. Coil tested within specs. Just a process of elimination. Ignition module getting replaced tomorrow. Sent from my iPhone using Tapatalk Share this post Link to post Share on other sites
Jkmacxf 24 Posted August 29, 2018 Timing has been set to 10deg BTDC the once the signal wire for the ecu is plugged back in goes to 14. Got me knackered. Sent from my iPhone using Tapatalk Share this post Link to post Share on other sites

Sent from my iPhone using TapatalkNo vac advance on EFI.All plug leads are on in right order (153624)?Vac leaks from gaskets/hoses/dipstick/oil cap cause big issues with the xflows injection so worth checking that tooSent from my Pixel using Tapatalk Share this post Link to post Share on other sites

Leads are in correct order. Sometimes it runs fine the breaks down. Noted the engine died when running and I removed the oil cap. I think the new module may fix it. I will post an update to what the fix is. Sent from my iPhone using Tapatalk Share this post Link to post Share on other sites
Jkmacxf 24 Posted September 1, 2018 Update Won’t start at all. threw a set of plugs and leads at it for cause they’re old. Tried new coil. Replaced module. Nothing. Will fire the die. Like it is being choked. Found one muffler rooted possibly blocking the exhaust. Dropping the exhaust off the car at the cat to see if it will start. Share this post Link to post Share on other sites
Jkmacxf 24 Posted September 1, 2018 Tested coolant temp sensor for ecu no reading at 20 deg supposed to be 2300 - 2700 ohms. Tested at 100deg supposed to be 170 - 210 is is showing around 6500. Oops. I have heard these will stop the engine. As it is now dead and won’t start. Sent from my iPhone using Tapatalk Share this post Link to post Share on other sites
SPArKy_Dave 8,873 Posted September 1, 2018 Replace the hall effect sensor inside the distributor... A faulty CTS won't help things, but shouldn't stop it from starting. 1 Jkmacxf reacted to this Share this post Link to post Share on other sites
Jkmacxf 24 Posted September 8, 2018 Original leads fried. Turns out I was sold the wrong set of leads. Shop reordered NGK leads fitted and runs perfectly. Can’t even remember brand supplied but they look like cheap crap. Xf Fairmont Ghia now the daily drive.
