Hi guys!
I an pretty new here, but not to my van. It‘s 5.9 **** build in 1991 and i did a complete transmission-overhaul myself already.

Right now i am kind of stuck with electrical issues.
When i start it up it cranks and ignites but as i let go the key it dies instantly. For the next igniting try i have to wait at least 4 seconds. Otherwise it will crank but not ignite.

Battery is in good condition.

Do have any ideas where to look for this pain-in-the-ass-failure?
Thanks,
Andy

Maybe look in the Engine Section instead if the Detail section---they can probably be of more help. If you wanna shine that van up we can help you here---

Might be a weak fuel pump. It'll cycle whenever you turn on the key to pressurize the system, but maybe it can't meet demand or you have an ignition switch or relay problem and it's not staying running.

Actually it starts on LPG. Did so for the last two years. LPG-System works fine, all ventiles open up vaporizer works also fine...
As i said, it starts and dies immediatly. But as it sounds not because of a lack of LPG. Its just „cut“ off.

Problem solved! All this was caused by bad ignition-cables. Just as a guess i ordered new ones. Today, after another hour of searching for anything, i got frustrated and installed them. After that it started right away and kept on running. Did several shutdowns and restarts. All fine!
