Crank, no start

[BigEd87]

I've got to 2008 Lucerne and it cranks fine but does not start. We test the fuel pump and it turns on. We replaced all three ignition coils because one of the three was cracked and did not register ohms through it. But still no joy.

Any other suggestions?

On the fuel pump it needs to have the pressure tested at the rail not just hearing it make noise.

Here's a post on troubleshooting the problem

Unfortunately it's not a one size fits all problem until items are confirmed good to be taken off the list.

I haven't tested the pressure yet but I have removed the front plugs and turned the engine over and smelled gas. Couldn't see any spark though.

I've also replaced the ignition control board as I thought that may be the issue. But it wasn't.

NO SPARK, THEN YOU WILL SMELL GAS! Rather than shooting the parts cannon at the problem, you need to do some testing! The following links may help you.

Turns out it was a fuse under the hood that was also burnt. The icm and the coils all needed to be replaced so I didn't end up wasting any money on parts. The main fuse box is under the back seat with the battery. Thanks for your help!

Which exact fuse? I’m having same issue crank no start and I replaced Icm, crank position sensor and all 3 coils, The only thing different is when I turn the key I noticed that the odometer and center cluster doesn’t light up

Man I wish I could remember exactly which fuse it was but it was the fuse box under the hood so you may just pull and inspect each one. There's not a lot so you can check them pretty quickly. I am pretty sure though that it was a standard rated fuse like 15 amp.
