Secondly, check if you can smell a strong diesel fuel odor. Check for a fuel leak, in case you find one then it might the root cause of the problem.

After your careful visual inspection resort to fixing it and then conduct a test using the diesel fuel pressure gauge to the fuel pressure. In case it lies outside the manufacturer’s specifications, then there might be a problem with your fuel pump. It might be clogged or have poor relay.
