My ZR1 cranks but wont start

[Don in VT]

Hi All,

We took the ZR on a 300 mile jaunt yesterday and everything went well. The Z ran like a clock. Great trip..

Went out just a few moments ago and the Z wont start. All the Z did was to sit in the garage overnignt. When I crank the engine it spins just fine but not start. When I turn the key on I can hear the FP run for 2 seconds but it really sounds rough, almost like a grinding noise. The noise is somewhat masked by the power antenna going up but I can still hear the pump. On a couple of tries, when I first turned the key to start, the motor caught once but still no start.

My fuel pump guage is locked up in the shop and I cant get it till tomorrow. I also need my scan tool and it is locked up too.

One thing I did do was to put my timing light on a spark plug leads and the ignition is firing on all plugs. It kinda looks like the FPs'
The forum and the FSM mention the single red lead near the CCM. If I power it up will it do any damage if I have a bad pump ?



Any comments or suggestions ?

Happy Fouth to you all,

Regards,
