[QUOTE="Maryland dieselnick, post: 1561960, member: 22661"] You need to go back to basics. Verify 5 volts at cps, ICP as a ref voltage. If they are not getting their 4.5 -5.0, it’s a no link and pulse width command becomes a no fire command. Don’t look at ICP in voltage for pressure. One can but. Look to that in pressure. If are ok in and about 48 in FICM and RPM, pressure is hinky but with no No start command in duty cycle, You gotta pull out the meter and look for those 5 volts and 12 IPR scanner show actual on FICM. You have a gremlin. Fuel will be no start, weak or fade-out. Be careful back at that IPR. It’s a skin stripper. [/QUOTE]
