420A Hard Start 420a '98 GS

[Jonnychance]

Anyone know about hard starts when my cars sits for awhile? I've already checked the obvious battery, alt., starter, changed spark plugs, changed coolant temp. Sensor.
I checked the voltage for the cam angle sensor 8volts for power and 5volts for the switch.
This is the only problem. Car drives perfect. Acceleration is perfect, same with idle. No dimming lights. It's only a hard start.

I would say it's probably a loss of fuel pressure, draining back through a worn fuel pump. This is usually the first indicator that a fuel pump needs to be replaced, and the pump can function well enough to properly run the engine in early stages. To test my theory, allow the car to sit for a while, then check the fuel pressure at the rail. A healthy fuel pump can hold steady pressure for 6 months, up to a year in my experience. If there is a drain back at the pump, it can happen in as quick as a few hours or a few days. A few weeks in early stages.

That’s what I thought but has 40psi to the rail an priming it or using starting fluid dosnt help unfortunately but tonight I’m gonna check my timing

Timing was on point I guess next will be junk yard

It was a bad starter. Every time I tested it the starter had just been used so it tested "good".
