dead 2004 se-r

I picked up a dead 04 se-r has light spark. The fuel pump is running the injectors are firing (wet plugs) has no start condition. Need some ideas on what to check.

Did you check for spark on all cylinders? Are they all weak?

Did you check the compression?

This. Check the compression. I just went through this with the Celica I bought to fix up and sell on. No start, had spark, fuel and air, but turns out it had super low compression numbers. You could also put about a teaspoon of oil in each cylinder, and see if it'll start.

Didn't those have problems with the cat disintegrating and getting sucked into the engine enough to ruin it? Id say checking the compression sounds like a good idea.

timing belt or chain? if belt, skipped teeth, or possibly missing teeth?

cam and crank sensors. Nissans of that vintage eat them for lunch...

That era sentra also like to drop butterfly valve hardware down in the intake manifold or high oil consumption. The QR is kind of a pile.

Nissans have all the problems listed above, but they also flood easily and lose compression as they wash the cylinders down. A tow start might be the easiest way if thats the case, but drying the plugs, oiling the cylinders and then pulling the fuel pump relay or fuse and cranking the hell out of it may do as well.

it an auto so pull start wont work. I have to find my compression tester it currently is hiding in my shop somewhere. I will give the oil a shot.

pulled all coils and here is what happens 1 spark ok and yellow next lighter then third no spark all cyl react the same. The compression tester is still mia going to buy one this weekend.

changed crank sensor good spark now still wont start. picking up a compression tester tomorrow.

Did a compression test. 20 30 30 10. No wonder it won't start.

Picked up a disassembled qr with a fresh shortblock jwt cams and balance shaft delete kit.

I think this will be my plan B challange car. What are the other shortcomings of this car?

Get rid of the stock header and precat (there's a decent chance that killed the first motor). An aftermarket header will get rid of the precat and give you a noticeable power bump too. Disassemble the intake manifold and remove, locktite and reinstall all of the screws in the "butterfly valves". I think you covered the other shortcoming earlier with "its an automatic". QR's make really good power even without boost, but they aren't the most robust engines in the world. As for making it fun, the best thing you can do for the handling is to shop until you find a Nismo rear sway bar, set it on full stiff and enjoy a front driver that will rotate. Sadly, if its an auto, you're missing out on the LSD, which really is a gem when combined with a car that turns. My autocross strategy was basically throw it into the corner, slide the rear end, mat the gas. It was surprisingly fast and, oh man, was it fun.

Unfortunately, I never really trusted the motor, even after fixing the common QR killers.

Pulled valve cover powered metal on top of cam bolts

I have started to pull the engine. Way too complicated, The amount of time I have in to this pull has passed the remove and replace time on the 05 civic engine I just replaced.

Its a Datsun...

Engine is out!! Removed the 2 valve keepers that I was missing for the replacement engine. Setting valve lash is a pain.

Assembling the replacement now. Have to love the engine is in totes purchase. It was Challenge friendly price though.

I am assembling the engine on a workbench and still can pick it up as a long block. I bet two guys could drop it in the engine bay. I carried the short block from the truck to the bench.

Stan, whats to going rate for dead sentra se-r's if you dont mind me asking? I see them in ma going for near 2k which i think is crazy.

We need an update

I bought this one for 600 and have seen a couple of spec v for 800-1200. Mine is just an auto ser.

I started a build thread.

Pssst... VQ35de...
