Hard starting still, replaced my GP relay
Troubleshot a GP relay problem last week. Replaced it (the old one fell apart at the incoming battery connection post) and it is now functional and I have not received any further GP fault indications. But I have to crank it for several seconds and then stop and retry to finally get my Excursion to start. I feel I must have bad glow plugs. It is better than before replacing the relay, but not right.
How hard are they to replace?
How difficult is it to determine which may be bad? I am thinking resistance checks, but I noticed that 2 are connected together at the GPR for the total of 4 sets.
Thanks in advance for any help,
