Takes several seconds to get truck started

[bigbad4x4]

I have an '01 7.3 and recently its getting real hard to start. It has fresh oil. new fuel filter, I pulled the codes using my DP tuner and it has a code p0541,
(manifold heater "A" low voltage) Could this be causing the hard start?? No smoke at all when it does start

[matter]

how is the starter? cranking strong?

It could be some of your glow plugs have burned out or the some of the wires in your head gaskets have bad connections. Have seen both. Fairly common in the 7.3. A new set of glow plugs are about 90 bucks. Not hard to put in either.

I just replaced the starter about 6 months ago, it spins over great, when it does start the rpm`s run up to around 2000 then drops to normal around 650, what about the code P0541? should I replace the manifold heater even though the temps here in La are around 80 deg @ 6am

Had an injector buzz test done all ck'd good, did a cylinder contribution test, #3 & #5 NOT contributing and the CPS voltage is dropping past 7 volts while cranking..


Thanx 4 all the help
